theora_png2theora: unrecognized option '--version' png2theora 1.1 Usage: png2theora [options] <input> The input argument uses C printf format to represent a list of files, i.e. file-%06d.png to look for files file000001.png to file9999999.png Options: -o --output <filename.ogv> file name for encoded output (required); -v --video-quality <n> Theora quality selector fro 0 to 10 (0 yields smallest files but lowest video quality. 10 yields highest fidelity but large files) -V --video-rate-target <n> bitrate target for Theora video --soft-target Use a large reservoir and treat the rate as a soft target; rate control is less strict but resulting quality is usually higher/smoother overall. Soft target also allows an optional -v setting to specify a minimum allowed quality. --two-pass Compress input using two-pass rate control This option performs both passes automatically. --first-pass <filename> Perform first-pass of a two-pass rate controlled encoding, saving pass data to <filename> for a later second pass --second-pass <filename> Perform second-pass of a two-pass rate controlled encoding, reading first-pass data from <filename>. The first pass data must come from a first encoding pass using identical input video to work properly. -k --keyframe-freq <n> Keyframe frequency -d --buf-delay <n> Buffer delay (in frames). Longer delays allow smoother rate adaptation and provide better overall quality, but require more client side buffering and add latency. The default value is the keyframe interval for one-pass encoding (or somewhat larger if --soft-target is used) and infinite for two-pass encoding. --chroma-444 Use 4:4:4 chroma subsampling --chroma-422 Use 4:2:2 chroma subsampling (4:2:0 is default) -s --aspect-numerator <n> Aspect ratio numerator, default is 0 -S --aspect-denominator <n> Aspect ratio denominator, default is 0 -f --framerate-numerator <n> Frame rate numerator -F --framerate-denominator <n> Frame rate denominator The frame rate nominator divided by this determines the frame rate in units per tick
