filtergraph is a description of the filtergraph, as described in the “Filtergraph syntax” section of the ffmpeg-filters manual. For simple graphs – those with one input and one output of the same type – see the -filter options. one with arbitrary number of inputs and/or outputs. ffmpeg -i input.mpg -timecode 01:02:03.04 -r 30000/1001 -s ntsc output.mpgĭefine a complex filtergraph, i.e. SEP is ’:’ for non drop timecode and ’ ’ (or ’.’) for drop. tag codec_tag ( input/output,per-stream)įorce a tag/fourcc for matching streams.-timecode hh: mm: ssSEP ff ffmpeg -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264įfmpeg -i file.mov -an -vn -bsf:s mov2textsub -c:s copy -f rawvideo sub.txt
Use the -bsfs option to get the list of bitstream filters. bitstream_filters is a comma-separated list of bitstream filters.
Set bitstream filters for matching streams. bsf bitstream_filters ( output,per-stream) For the situation where multiple output files exist, a streamid may be reassigned to a different value.įor example, to set the stream 0 PID to 33 and the stream 1 PID to 36 for an output mpegts file: ffmpeg -i inurl -streamid 0:33 -streamid 1:36 out.ts This option should be specified prior to the output filename to which it applies. Set the initial demux-decode delay.-streamid output-stream-index: new-value ( output)Īssign a new stream-id value to an output stream. Set the maximum demux-decode delay.-muxpreload seconds ( output) This threshold use to discard crazy/damaged timestamps and the default is 30 hours which is arbitrarily picked and quite conservative.-muxdelay seconds ( output) Timestamp discontinuity delta threshold.-dts_error_threshold seconds 0.04166, 2.0833e-5)ĭefault value is 0.-bitexact ( input/output)Įnable bitexact mode for (de)muxer and (de/en)coder-shortest ( output)įinish encoding when the shortest input stream ends.-dts_delta_threshold 1:24, 1:48000) or as a floating point number (e.g. This field can be provided as a ratio of two integers (e.g.
