NAMEffserver - ffserver video server
DESCRIPTIONffserver is a streaming server for both audio and video. It supports several live feeds, streaming from files and time shifting on live feeds. You can seek to positions in the past on each live feed, provided you specify a big enough feed storage.
ffserver is configured through a configuration file, which is read at startup. If not explicitly specified, it will read from /etc/ffserver.conf.
ffserver receives prerecorded files or
An ffserver instance will listen on some port as specified in the configuration file. You can launch one or more instances of ffmpeg and send one or more
Input streams are called feeds, and each one is specified by a "<Feed>" section in the configuration file.
For each feed you can have different output streams in various formats, each one specified by a "<Stream>" section in the configuration file.
DETAILED DESCRIPTIONffserver works by forwarding streams encoded by ffmpeg, or pre-recorded streams which are read from disk.
Precisely, ffserver acts as an
A feed is an
Each feed is identified by a unique name, corresponding to the name of the resource published on ffserver, and is configured by a dedicated "Feed" section in the configuration file.

Each feed is associated to a file which is stored on disk. This stored file is used to send pre-recorded data to a player as fast as possible when new content is added in real-time to the stream.
A ``live-stream'' or ``stream'' is a resource published by ffserver, and made accessible through the
A stream can be connected to a feed, or to a file. In the first case, the published stream is forwarded from the corresponding feed generated by a running instance of ffmpeg, in the second case the stream is read from a pre-recorded file.
Each stream is identified by a unique name, corresponding to the name of the resource served by ffserver, and is configured by a dedicated "Stream" section in the configuration file.
The stream access

stream_name is the name of the corresponding stream defined in the configuration file. options is a list of options specified after the
In case the stream is associated to a feed, the encoding parameters must be configured in the stream configuration. They are sent to ffmpeg when setting up the encoding. This allows ffserver to define the encoding parameters used by the ffmpeg encoders.
The ffmpeg override_ffserver commandline option allows one to override the encoding parameters set by the server.
Multiple streams can be connected to the same feed.
For example, you can have a situation described by the following graph:
_________ __________ | | | | ffmpeg 1 -----| feed 1 |-----| stream 1 | \ |_________|\ |__________| \ \ \ \ __________ \ \ | | \ \| stream 2 | \ |__________| \ \ _________ __________ \ | | | | \| feed 2 |-----| stream 3 | |_________| |__________| _________ __________ | | | | ffmpeg 2 -----| feed 3 |-----| stream 4 | |_________| |__________| _________ __________ | | | | | file 1 |-----| stream 5 | |_________| |__________|
FFM, FFM2 formats

Simply point your browser to the address of the special status stream specified in the configuration file.
For example if you have:
<Stream status.html> Format status # Only allow local people to get the status ACL allow localhost ACL allow 192.168.0.0 192.168.255.255 </Stream>
then the server will post a page with the status information when the special stream status.html is requested.
How do I make it work?As a simple test, just run the following two command lines where
ffserver -f doc/ffserver.conf & ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
At this point you should be able to go to your Windows machine and fire up Windows Media Player (
You should (after a short delay) see video and hear audio.
You should edit the ffserver.conf file to suit your needs (in terms of frame rates etc). Then install ffserver and ffmpeg, write a script to start them up, and off you go.
What else can it do?You can replay video from .ffm files that was recorded earlier. However, there are a number of caveats, including the fact that the ffserver parameters must match the original parameters used to record the file. If they do not, then ffserver deletes the file before recording into it. (Now that I write this, it seems broken).
You can fiddle with many of the codec choices and encoding parameters, and there are a bunch more parameters that you cannot control. Post a message to the mailing list if there are some 'must have' parameters. Look in ffserver.conf for a list of the currently available controls.
It will automatically generate the
Tips* When you connect to a live stream, most players (
You can also add a 'Preroll 15' statement into the ffserver.conf that will add the 15 second prebuffering on all requests that do not otherwise specify a time. In addition, ffserver will skip frames until a key_frame is found. This further reduces the startup delay by not transferring data that will be discarded.
Why does the ?buffer / Preroll stop working after a time?It turns out that (on my machine at least) the number of frames successfully grabbed is marginally less than the number that ought to be grabbed. This means that the timestamp in the encoded data stream gets behind realtime. This means that if you say 'Preroll 10', then when the stream gets 10 or more seconds behind, there is no Preroll left.
Fixing this requires a change in the internals of how timestamps are handled.
Does the ?date= stuff work.Yes (subject to the limitation outlined above). Also note that whenever you start ffserver, it deletes the ffm file (if any parameters have changed), thus wiping out what you had recorded before.
The format of the "?date=xxxxxx" is fairly flexible. You should use one of the following formats (the 'T' is literal):
* YYYY-MM-DDTHH:MM:SS (localtime) * YYYY-MM-DDTHH:MM:SSZ (UTC)
You can omit the YYYY-MM-DD, and then it refers to the current day. However note that ?date=16:00:00 refers to 16:00 on the current day --- this may be in the future and so is unlikely to be useful.
You use this by adding the ?date= to the end of the
OPTIONSAll the numerical options, if not specified otherwise, accept a string representing a number as input, which may be followed by one of the
If 'i' is appended to the
Options which do not take arguments are boolean options, and set the corresponding value to true. They can be set to false by prefixing the option name with ``no''. For example using ``-nofoo'' will set the boolean option with name ``foo'' to false.
Stream specifiersSome options are applied per-stream, e.g. bitrate or codec. Stream specifiers are used to precisely specify which stream(s) a given option belongs to.
A stream specifier is a string generally appended to the option name and separated from it by a colon. E.g. "-codec:a:1 ac3" contains the "a:1" stream specifier, which matches the second audio stream. Therefore, it would select the ac3 codec for the second audio stream.
A stream specifier can match several streams, so that the option is applied to all of them. E.g. the stream specifier in "-b:a 128k" matches all audio streams.
An empty stream specifier matches all streams. For example, "-codec copy" or "-codec: copy" would copy all the streams without reencoding.
Possible forms of stream specifiers are:
- Matches the stream with this index. E.g. "-threads:1 4" would set the thread count for the second stream to 4.
- stream_type is one of following: 'v' or 'V' for video, 'a' for audio, 's' for subtitle, 'd' for data, and 't' for attachments. 'v' matches all video streams, 'V' only matches video streams which are not attached pictures, video thumbnails or cover arts. If stream_index is given, then it matches stream number stream_index of this type. Otherwise, it matches all streams of this type.
- If stream_index is given, then it matches the stream with number stream_index in the program with the id program_id. Otherwise, it matches all streams in the program.
- #stream_id or i:stream_id
Match the stream by stream id (e.g. PIDin MPEG-TS container).
- Matches streams with the metadata tag key having the specified value. If value is not given, matches streams that contain the given tag with any value.
Matches streams with usable configuration, the codec must be defined and the
essential information such as video dimension or audio sample rate must be present.
Note that in ffmpeg, matching by metadata will only work properly for input files.
Generic optionsThese options are shared amongst the ff* tools.
- Show license.
- -h, -?, -help, --help [arg]
Show help. An optional parameter may be specified to print help about a specific
item. If no argument is specified, only basic (non advanced) tool
options are shown.
Possible values of arg are:
- Print advanced tool options in addition to the basic tool options.

Show all codecs known to libavcodec.
Note that the term 'codec' is used throughout this documentation as a shortcut for what is more correctly called a media bitstream format.
- Show available decoders.
- Show all available encoders.
- Show available bitstream filters.
- Show available protocols.
- Show available libavfilter filters.

- -sources device[,opt1=val1[,opt2=val2]...]
Show autodetected sources of the intput device.
Some devices may provide system-dependent source names that cannot be autodetected.
The returned list cannot be assumed to be always complete.
ffmpeg -sources pulse,server=192.168.0.4
- -sinks device[,opt1=val1[,opt2=val2]...]
Show autodetected sinks of the output device.
Some devices may provide system-dependent sink names that cannot be autodetected.
The returned list cannot be assumed to be always complete.
ffmpeg -sinks pulse,server=192.168.0.4
- -loglevel [repeat+]loglevel | -v [repeat+]loglevel
Set the logging level used by the library.
Adding ``repeat+'' indicates that repeated log output should not be compressed
to the first line and the ``Last message repeated n times'' line will be
omitted. ``repeat'' can also be used alone.
If ``repeat'' is used alone, and with no prior loglevel set, the default
loglevel will be used. If multiple loglevel parameters are given, using
'repeat' will not change the loglevel.
loglevel is a string or a number containing one of the following values:
- quiet, -8
- Show nothing at all; be silent.
- panic, 0
- Only show fatal errors which could lead the process to crash, such as an assertion failure. This is not currently used for anything.
- fatal, 8
- Only show fatal errors. These are errors after which the process absolutely cannot continue.
- error, 16
- Show all errors, including ones which can be recovered from.
- warning, 24
- Show all warnings and errors. Any message related to possibly incorrect or unexpected events will be shown.
- info, 32
- Show informative messages during processing. This is in addition to warnings and errors. This is the default value.
- verbose, 40
- Same as "info", except more verbose.
- debug, 48
- Show everything, including debugging information.
- trace, 56
By default the program logs to stderr. If coloring is supported by the terminal, colors are used to mark errors and warnings. Log coloring can be disabled setting the environment variableAV_LOG_FORCE_NOCOLORorNO_COLOR, or can be forced setting the environment variableAV_LOG_FORCE_COLOR. The use of the environment variableNO_COLORis deprecated and will be dropped in a future FFmpeg version.
Dump full command line and console output to a file named
"program-YYYYMMDD-HHMMSS.log" in the current
This file can be useful for bug reports.
It also implies "-loglevel verbose".
Setting the environment variableFFREPORTto any value has the same effect. If the value is a ':'-separated key=value sequence, these options will affect the report; option values must be escaped if they contain special characters or the options delimiter ':' (see the ``Quoting and escaping'' section in the ffmpeg-utils manual).
The following options are recognized:
- set the file name to use for the report; %p is expanded to the name of the program, %t is expanded to a timestamp, "%%" is expanded to a plain "%"
- set the log verbosity level using a numerical value (see "-loglevel").
For example, to output a report to a file named ffreport.log using a log level of 32 (alias for log level "info"):
FFREPORT=file=ffreport.log:level=32 ffmpeg -i input output
Errors in parsing the environment variable are not fatal, and will not appear in the report.
Suppress printing banner.
All FFmpeg tools will normally show a copyright notice, build options and library versions. This option can be used to suppress printing this information.
- -cpuflags flags (global)
Allows setting and clearing cpu flags. This option is intended
for testing. Do not use it unless you know what you're doing.
ffmpeg -cpuflags -sse+mmx ... ffmpeg -cpuflags mmx ... ffmpeg -cpuflags 0 ...
Possible flags for this option are:
- Specific Processors
This option is used to benchmark all available OpenCL devices and print the
results. This option is only available when FFmpeg has been compiled with
When FFmpeg is configured with "--enable-opencl", the options for the global OpenCL context are set via -opencl_options. See the ``OpenCL Options'' section in the ffmpeg-utils manual for the complete list of supported options. Amongst others, these options include the ability to select a specific platform and device to run the OpenCL code on. By default, FFmpeg will run on the first device of the first platform. While the options for the global OpenCL context provide flexibility to the user in selecting the OpenCL device of their choice, most users would probably want to select the fastest OpenCL device for their system.
This option assists the selection of the most efficient configuration by identifying the appropriate device for the user's system. The built-in benchmark is run on all the OpenCL devices and the performance is measured for each device. The devices in the results list are sorted based on their performance with the fastest device listed first. The user can subsequently invoke ffmpeg using the device deemed most appropriate via -opencl_options to obtain the best performance for the OpenCL accelerated code.
Typical usage to use the fastest OpenCL device involve the following steps.
Run the command:
Note down the platformID(pidx) and deviceID(didx) of the first i.e. fastest device in the list. Select the platform and device using the command:
ffmpeg -opencl_options platform_idx=<pidx>:device_idx=<didx> ...
- -opencl_options options (global)
Set OpenCL environment options. This option is only available when
FFmpeg has been compiled with "--enable-opencl".
options must be a list of key=value option pairs separated by ':'. See the ``OpenCL Options'' section in the ffmpeg-utils manual for the list of supported options.
AVOptionsThese options are provided directly by the libavformat, libavdevice and libavcodec libraries. To see the list of available AVOptions, use the -help option. They are separated into two categories:
- These options can be set for any container, codec or device. Generic options are listed under AVFormatContext options for containers/devices and under AVCodecContext options for codecs.
- These options are specific to the given container, device or codec. Private options are listed under their corresponding containers/devices/codecs.
For example to write an ID3v2.3 header instead of a default ID3v2.4 to an
ffmpeg -i input.flac -id3v2_version 3 out.mp3
All codec AVOptions are per-stream, and thus a stream specifier should be attached to them.
Note: the -nooption syntax cannot be used for boolean AVOptions, use -option 0/-option 1.
Note: the old undocumented way of specifying per-stream AVOptions by prepending v/a/s to the options name is now obsolete and will be removed soon.
- -f configfile
- Read configuration file configfile. If not specified it will read by default from /etc/ffserver.conf.
- Enable no-launch mode. This option disables all the "Launch" directives within the various "<Feed>" sections. Since ffserver will not launch any ffmpeg instances, you will have to launch them manually.
- Enable debug mode. This option increases log verbosity, and directs log messages to stdout. When specified, the CustomLog option is ignored.
CONFIGURATION FILE SYNTAXffserver reads a configuration file containing global options and settings for each stream and feed.
The configuration file consists of global options and dedicated sections, which must be introduced by "<
Currently the following sections are recognized: Feed, Stream, Redirect.
A line starting with "#" is ignored and treated as a comment.
Name of options and sections are case-insensitive.
It accepts the folling forms
Allow/deny access to address.
ACL ALLOW <address> ACL DENY <address>
Allow/deny access to ranges of addresses from first_address to
ACL ALLOW <first_address> <last_address> ACL DENY <first_address> <last_address>
You can repeat the
- HTTPPort port_number
- Port port_number
- RTSPPort port_number
HTTPPort sets the HTTPserver listeningTCPport number, RTSPPort sets theRTSPserver listeningTCPport number.
Port is the equivalent of HTTPPort and is deprecated.
You must select a different port from your standardHTTPweb server if it is running on the same computer.
If not specified, no corresponding server will be created.
- HTTPBindAddress ip_address
- BindAddress ip_address
- RTSPBindAddress ip_address
Set address on which the HTTP/RTSPserver is bound. Only useful if you have several network interfaces.
BindAddress is the equivalent of HTTPBindAddress and is deprecated.
- MaxHTTPConnections n
Set number of simultaneous HTTPconnections that can be handled. It has to be defined before the MaxClients parameter, since it defines the MaxClients maximum limit.
Default value is 2000.
- MaxClients n
Set number of simultaneous requests that can be handled. Since
ffserver is very fast, it is more likely that you will want
to leave this high and use MaxBandwidth.
Default value is 5.
- MaxBandwidth kbps
Set the maximum amount of kbit/sec that you are prepared to consume
when streaming to clients.
Default value is 1000.
- CustomLog filename
Set access log file (uses standard Apache log file format). '-' is the
If not specified ffserver will produce no log.
In case the commandline option -d is specified this option is ignored, and the log is written to standard output.
- Set no-daemon mode. This option is currently ignored since now ffserver will always work in no-daemon mode, and is deprecated.
- Control whether default codec options are used for the all streams or not. Each stream may overwrite this setting for its own. Default is UseDefaults. The lastest occurrence overrides previous if multiple definitions.
Feed sectionA Feed section defines a feed provided to ffserver.
Each live feed contains one video and/or audio sequence coming from an ffmpeg encoder or another ffserver. This sequence may be encoded simultaneously with several codecs at several resolutions.
A feed instance specification is introduced by a line in the form:
The following options are recognized within a Feed section.
- File filename
- ReadOnlyFile filename
Set the path where the feed file is stored on disk.
If not specified, the /tmp/FEED.ffm is assumed, whereFEEDis the feed name.
If ReadOnlyFile is used the file is marked as read-only and it will not be deleted or updated.
- Truncate the feed file, rather than appending to it. By default ffserver will append data to the file, until the maximum file size value is reached (see FileMaxSize option).
- FileMaxSize size
Set maximum size of the feed file in bytes. 0 means unlimited. The
postfixes "K" (2^10), "M" (2^20), and "G" (2^30) are
Default value is 5M.
- Launch args
Launch an ffmpeg command when creating ffserver.
args must be a sequence of arguments to be provided to an ffmpeg instance. The first provided argument is ignored, and it is replaced by a path with the same dirname of the ffserver instance, followed by the remaining argument and terminated with a path corresponding to the feed.
When the launched process exits, ffserver will launch another program instance.
In case you need a more complex ffmpeg configuration, e.g. if you need to generate multipleFFMfeeds with a single ffmpeg instance, you should launch ffmpeg by hand.
This option is ignored in case the commandline option -n is specified.
Specify the list of IPaddress which are allowed or denied to write the feed. MultipleACLoptions can be specified.
Stream sectionA Stream section defines a stream provided by ffserver, and identified by a single name.
The stream is sent when answering a request containing the stream name.
A stream section must be introduced by the line:
The following options are recognized within a Stream section.
Encoding options are marked with the encoding tag, and they are used to set the encoding parameters, and are mapped to libavcodec encoding options. Not all encoding options are supported, in particular it is not possible to set encoder private options. In order to override the encoding options specified by ffserver, you can use the ffmpeg override_ffserver commandline option.
Only one of the Feed and File options should be set.
- Feed feed_name
Set the input feed. feed_name must correspond to an existing
feed defined in a "Feed" section.
When this option is set, encoding options are used to setup the encoding operated by the remote ffmpeg process.
- File filename
Set the filename of the pre-recorded input file to stream.
When this option is set, encoding options are ignored and the input file content is re-streamed as is.
- Format format_name
Set the format of the output stream.
Must be the name of a format recognized by FFmpeg. If set to status, it is treated as a status stream.
- InputFormat format_name
- Set input format. If not specified, it is automatically guessed.
- Preroll n
Set this to the number of seconds backwards in time to start. Note that
most players will buffer 5-10 seconds of video, and also you need to allow
for a keyframe to appear in the data stream.
Default value is 0.
- Do not send stream until it gets the first key frame. By default ffserver will send data immediately.
- MaxTime n
Set the number of seconds to run. This value set the maximum duration
of the stream a client will be able to receive.
A value of 0 means that no limit is set on the stream duration.
Set ACLfor the stream.
- DynamicACL spec
- RTSPOption option
- MulticastAddress address
- MulticastPort port
- MulticastTTL integer
- FaviconURL url
- Set favicon (favourite icon) for the server status page. It is ignored for regular streams.
- Author value
- Comment value
- Copyright value
- Title value
- Set metadata corresponding to the option. All these options are deprecated in favor of Metadata.
