Hello there, How would one pass an option to an underlying muxer when using a fifo output?
Take this example: https://stackoverflow.com/questions/41880004/ffmpeg-how-to-stream-to-multiple-outputs-with-the-same-encoding-independently/42111569 Wherein you have outputs like these: -i ... -f tee "[onfail=ignore]'C:\Users\blablabla.mp4'| [f=fifo:fifo_format=flv:drop_pkts_on_overflow=1:attempt_recovery=1:recovery_wait_time=1]rtmp://yourServer...| [f=fifo:fifo_format=flv:drop_pkts_on_overflow=1:attempt_recovery=1:recovery_wait_time=1]"rtmp://facebook..." Assume that the underlying muxer, say mp4, has private options that you want passed to from within a fifo output as shown above with the flv outputs: ffmpeg -h muxer=mp4 Muxer mp4 [MP4 (MPEG-4 Part 14)]: Common extensions: mp4. Mime type: video/mp4. Default video codec: mpeg4. Default audio codec: aac. mp4 muxer AVOptions: -movflags <flags> E........ MOV muxer flags (default 0) rtphint E........ Add RTP hint tracks empty_moov E........ Make the initial moov atom empty frag_keyframe E........ Fragment at video keyframes frag_every_frame E........ Fragment at every frame separate_moof E........ Write separate moof/mdat atoms for each track frag_custom E........ Flush fragments on caller requests isml E........ Create a live smooth streaming feed (for pushing to a publishing point) faststart E........ Run a second pass to put the index (moov atom) at the beginning of the file omit_tfhd_offset E........ Omit the base data offset in tfhd atoms disable_chpl E........ Disable Nero chapter atom default_base_moof E........ Set the default-base-is-moof flag in tfhd atoms dash E........ Write DASH compatible fragmented MP4 frag_discont E........ Signal that the next fragment is discontinuous from earlier ones delay_moov E........ Delay writing the initial moov until the first fragment is cut, or until the first fragment flush global_sidx E........ Write a global sidx index at the start of the file skip_sidx E........ Skip writing of sidx atom write_colr E........ Write colr atom (Experimental, may be renamed or changed, do not use from scripts) write_gama E........ Write deprecated gama atom use_metadata_tags E........ Use mdta atom for metadata. skip_trailer E........ Skip writing the mfra/tfra/mfro trailer for fragmented files negative_cts_offsets E........ Use negative CTS offsets (reducing the need for edit lists) -moov_size <int> E........ maximum moov size so it can be placed at the begin (from 0 to INT_MAX) (default 0) -rtpflags <flags> E........ RTP muxer flags (default 0) latm E........ Use MP4A-LATM packetization instead of MPEG4-GENERIC for AAC rfc2190 E........ Use RFC 2190 packetization instead of RFC 4629 for H.263 skip_rtcp E........ Don't send RTCP sender reports h264_mode0 E........ Use mode 0 for H.264 in RTP send_bye E........ Send RTCP BYE packets when finishing -skip_iods <boolean> E........ Skip writing iods atom. (default true) -iods_audio_profile <int> E........ iods audio profile atom. (from -1 to 255) (default -1) -iods_video_profile <int> E........ iods video profile atom. (from -1 to 255) (default -1) -frag_duration <int> E........ Maximum fragment duration (from 0 to INT_MAX) (default 0) -min_frag_duration <int> E........ Minimum fragment duration (from 0 to INT_MAX) (default 0) -frag_size <int> E........ Maximum fragment size (from 0 to INT_MAX) (default 0) -ism_lookahead <int> E........ Number of lookahead entries for ISM files (from 0 to INT_MAX) (default 0) -video_track_timescale <int> E........ set timescale of all video tracks (from 0 to INT_MAX) (default 0) -brand <string> E........ Override major brand -use_editlist <boolean> E........ use edit list (default auto) -fragment_index <int> E........ Fragment number of the next fragment (from 1 to INT_MAX) (default 1) -mov_gamma <float> E........ gamma value for gama atom (from 0 to 10) (default 0) -frag_interleave <int> E........ Interleave samples within fragments (max number of consecutive samples, lower is tighter interleaving, but with more overhead) (from 0 to INT_MAX) (default 0) -encryption_scheme <string> E........ Configures the encryption scheme, allowed values are none, cenc-aes-ctr -encryption_key <binary> E........ The media encryption key (hex) -encryption_kid <binary> E........ The media encryption key identifier (hex) -use_stream_ids_as_track_ids <boolean> E........ use stream ids as track ids (default false) -write_tmcd <boolean> E........ force or disable writing tmcd (default auto) -write_prft <int> E........ Write producer reference time box with specified time source (from 0 to 2) (default 0) wallclock E........ pts E........ -empty_hdlr_name <boolean> E........ write zero-length name string in hdlr atoms within mdia and minf atoms (default false) How would one accomplish that, in such a setup?
