Usage MP4Client [options] [filename] -c fileName: user-defined configuration file. Also works with -cfg -rti fileName: logs run-time info (FPS, CPU, Mem usage) to file -rtix fileName: same as -rti but driven by GPAC logs -quiet: removes script message, buffering and downloading status -strict-error: exit when the player reports its first error -opt option: Overrides an option in the configuration file. String format is section:key=value. "section:key=null" removes the key "section:*=null" removes the section -conf option: Same as -opt but does not start player. -log-file file: sets output log file. Also works with -lf -logs log_args: sets log tools and levels, formatted as a ':'-separated list of toolX[:toolZ]@levelX levelX can be one of: "quiet" : skip logs "error" : logs only error messages "warning" : logs error+warning messages "info" : logs error+warning+info messages "debug" : logs all messages toolX can be one of: "core" : libgpac core "coding" : bitstream formats (audio, video, scene) "container" : container formats (ISO File, MPEG-2 TS, AVI, ...) "network" : network data exept RTP trafic "rtp" : rtp trafic "author" : authoring tools (hint, import, export) "sync" : terminal sync layer "codec" : terminal codec messages "parser" : scene parsers (svg, xmt, bt) and other "media" : terminal media object management "scene" : scene graph and scene manager "script" : scripting engine messages "interact" : interaction engine (events, scripts, etc) "smil" : SMIL timing engine "compose" : composition engine (2D, 3D, etc) "mmio" : Audio/Video HW I/O management "rti" : various run-time stats "cache" : HTTP cache subsystem "audio" : Audio renderer and mixers "dash" : HTTP streaming logs "module" : GPAC modules debugging "mutex" : mutex "all" : all tools logged - other tools can be specified afterwards. -log-clock or -lc : logs time in micro sec since start time of GPAC before each log line. -log-utc or -lu : logs UTC time in ms before each log line. -ifce IPIFCE : Sets default Multicast interface -size WxH: specifies visual size (default: scene size) -no-thread: disables thread usage (except for audio) -no-compositor-thread: disables compositor thread (iOS and Android mode) -no-audio: disables audio -no-wnd: uses windowless mode (Win32 only) -no-back: uses transparent background for output window when no background is specified (Win32 only) -align vh: specifies v and h alignment for windowless mode possible v values: t(op), m(iddle), b(ottom) possible h values: l(eft), m(iddle), r(ight) default alignment is top-left default alignment is top-left -pause: pauses at first frame -play-from T: starts from T seconds in media -speed S: starts with speed S -loop: loops presentation -no-regulation: disables framerate regulation -bench: disable a/v output and bench source decoding (as fast as possible) -vbench: disable audio output, video sync bench source decoding/display (as fast as possible) -sbench: disable all decoders and bench systems layer (as fast as possible) -fs: starts in fullscreen mode -views v1:.:vN: creates an auto-stereo scene of N views. vN can be any type of URL supported by GPAC. in this mode, URL argument of GPAC is ignored, GUI as well. this is equivalent as using views://v1:.:N as an URL. -exit: automatically exits when presentation is over -run-for TIME: runs for TIME seconds and exits -service ID: auto-tune to given service ID in a multiplex -noprog: disable progress report -no-save: disable saving config file on exit -no-addon: disable automatic loading of media addons declared in source URL -gui: starts in GUI mode. The GUI is indicated in GPAC config, section General, by the key [StartupFile] Dumper Options (times is a formated as start-end, with start being sec, h:m:s:f/fps or h:m:s:ms): -bmp [times]: dumps given frames to bmp -png [times]: dumps given frames to png -raw [times]: dumps given frames to raw -avi [times]: dumps given file to raw avi -sha [times]: dumps given file to raw SHA-1 (1 hash per frame) -out filename: name of the output file -rgbds: dumps the RGBDS pixel format texture with -avi [times]: dumps an rgbds-format .avi -rgbd: dumps the RGBD pixel format texture with -avi [times]: dumps an rgbd-format .avi -depth: dumps depthmap (z-buffer) frames with -avi [times]: dumps depthmap in grayscale .avi with -bmp: dumps depthmap in grayscale .bmp with -png: dumps depthmap in grayscale .png -fps FPS: specifies frame rate for AVI dumping (default: 25.000000) -scale s: scales the visual size (default: 1) -fill: uses fill aspect ratio for dumping (default: none) -show: shows window while dumping (default: no) -help: shows this screen MP4Client - GPAC command line player and dumper - version 0.5.2-DEV-revVersion: 0.5.2-426-gc5ad4e4+dfsg5-3 GPAC Written by Jean Le Feuvre (c) 2001-2005 - ENST (c) 2005-200X GPAC Configuration: --build=x86_64-linux-gnu --prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --disable-silent-rules --libdir=${prefix}/lib/x86_64-linux-gnu --libexecdir=${prefix}/lib/x86_64-linux-gnu --disable-maintainer-mode --disable-dependency-tracking --prefix=/usr --libdir=lib/x86_64-linux-gnu --mandir=${prefix}/share/man --extra-cflags=-Wall -fPIC -DPIC -I/usr/include/mozjs -DXP_UNIX -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector-strong -Wformat -Werror=format-security --extra-ldflags=-Wl,-Bsymbolic-functions -Wl,-z,relro --enable-joystick --enable-debug --disable-ssl --verbose Features: GPAC_64_BITS GPAC_HAS_JPEG GPAC_HAS_PNG
