#11501: The tee and fifo muxers do not respect the -program parameter(s) with mpegts -------------------------------------+------------------------------------- Reporter: Dennis E. | Type: defect Mungai | Status: new | Priority: critical Component: avformat | Version: git- Keywords: tee fifo | master mpegts | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- **Summary of the bug:** As the subject matter infers. FFmpeg does not respect the {{{-program}}} parameter combination(s) with the underlying mpegts muxer(s) when it's called up from either {{{tee}}} or the {{{fifo}}} muxer(s).
A trivial example where this works perfectly with the mpegts muxer to create multiple PMTs associated with an audio & video stream pair is shown below: {{{ ffmpeg -init_hw_device cuda=cu:0 \ -filter_hw_device cu \ -thread_queue_size 5120 -f lavfi -i testsrc=duration=360:size=1920x1080:rate=60 \ -thread_queue_size 5120 -f lavfi -i "sine=frequency=2000:duration=360" \ -filter_complex \ "[0:v]hwupload,scale_cuda[v1]; \ [v1]split=2[v2][v3]; \ [1:a]asplit=2[a1][a2]" \ -c:a libfdk_aac -b:a 128k -ar 48000 -ac 2 \ -b:v:0 1250k -minrate:v:0 1250k -maxrate:v:0 1250k -bufsize:v:0 1250k -c:v:0 h264_nvenc \ -no-scenecut:v:0 1 -r:v:0 60 -g:v:0 120 -tune:v:0 hq -rc:v:0 cbr -preset:v:0 p4 -bf:v:0 0 \ -b:v:1 1000k -minrate:v:1 1000k -maxrate:v:1 1000k -bufsize:v:1 1000k -c:v:1 h264_nvenc \ -no-scenecut:v:1 1 -r:v:1 60 -g:v:1 120 -tune:v:1 hq -rc:v:1 cbr -preset:v:1 p4 -bf:v:1 0 \ -noautoscale -flags +global_header+cgop \ -map "[v2]" -map "[v3]" -map "[a1]" -map "[a2]" \ -program title="Stream 1":st=0:st=1 \ -program title="Stream 2":st=2:st=3 \ -max_muxing_queue_size 5120 \ -flags -global_header+cgop -f mpegts \ "dump_stream.ts" }}} {{{ffprobe}}} confirms the correct creation of the PMTs and the associated streams: {{{ Input #0, mpegts, from 'dump_stream.ts': Duration: 00:06:00.00, start: 1.400000, bitrate: 3018 kb/s Program 1 Metadata: service_name : Stream 1 service_provider: FFmpeg Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg/unknown/unknown, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn Stream #0:1[0x101]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg/unknown/unknown, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn Program 2 Metadata: service_name : Stream 2 service_provider: FFmpeg Stream #0:2[0x102]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 128 kb/s Stream #0:3[0x103]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 128 kb/s }}} Now, attempting the same with the {{{tee}}} and/or {{{fifo}}} muxer(s), independently or combined, and with the {{{-program}}} parameter(s) defined globally as shown in the trivial example below: {{{ ffmpeg -init_hw_device cuda=cu:0 \ -filter_hw_device cu \ -thread_queue_size 5120 -f lavfi -i testsrc=duration=360:size=1920x1080:rate=60 \ -thread_queue_size 5120 -f lavfi -i "sine=frequency=2000:duration=360" \ -filter_complex \ "[0:v]hwupload,scale_cuda[v1]; \ [v1]split=2[v2][v3]; \ [1:a]asplit=2[a1][a2]" \ -c:a libfdk_aac -b:a 128k -ar 48000 -ac 2 \ -b:v:0 1250k -minrate:v:0 1250k -maxrate:v:0 1250k -bufsize:v:0 1250k -c:v:0 h264_nvenc \ -no-scenecut:v:0 1 -r:v:0 60 -g:v:0 120 -tune:v:0 hq -rc:v:0 cbr -preset:v:0 p4 -bf:v:0 0 \ -b:v:1 1000k -minrate:v:1 1000k -maxrate:v:1 1000k -bufsize:v:1 1000k -c:v:1 h264_nvenc \ -no-scenecut:v:1 1 -r:v:1 60 -g:v:1 120 -tune:v:1 hq -rc:v:1 cbr -preset:v:1 p4 -bf:v:1 0 \ -noautoscale -flags +global_header+cgop \ -map "[v2]" -map "[v3]" -map "[a1]" -map "[a2]" \ -program title="Stream 1":st=0:st=1 \ -program title="Stream 2":st=2:st=3 \ -max_muxing_queue_size 5120 \ -flags -global_header+cgop \ -f tee "[f=mpegts]dump_stream.ts" }}} Results in this output from {{{ffprobe}}}: {{{ ffmpeg Input #0, mpegts, from 'dump_stream.ts': Duration: 00:06:00.04, start: 0.000000, bitrate: 3020 kb/s Program 1 Metadata: service_name : Service01 service_provider: FFmpeg Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg/unknown/unknown, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn Stream #0:1[0x101]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt470bg/unknown/unknown, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 60 fps, 60 tbr, 90k tbn Stream #0:2[0x102]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 128 kb/s Stream #0:3[0x103]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 48000 Hz, stereo, fltp, 128 kb/s }}} Demonstrating that only one PMT is created, with all the streams bundled therein. Attempting to pass these {{{-program}}} parameters directly to the underlying mpegts muxer(s) called by either tee or fifo, as shown below: {{{ ffmpeg -init_hw_device cuda=cu:0 \ -filter_hw_device cu \ -thread_queue_size 5120 -f lavfi -i testsrc=duration=360:size=1920x1080:rate=60 \ -thread_queue_size 5120 -f lavfi -i "sine=frequency=2000:duration=360" \ -filter_complex \ "[0:v]hwupload,scale_cuda[v1]; \ [v1]split=2[v2][v3]; \ [1:a]asplit=2[a1][a2]" \ -c:a libfdk_aac -b:a 128k -ar 48000 -ac 2 \ -b:v:0 1250k -minrate:v:0 1250k -maxrate:v:0 1250k -bufsize:v:0 1250k -c:v:0 h264_nvenc \ -no-scenecut:v:0 1 -r:v:0 60 -g:v:0 120 -tune:v:0 hq -rc:v:0 cbr -preset:v:0 p4 -bf:v:0 0 \ -b:v:1 1000k -minrate:v:1 1000k -maxrate:v:1 1000k -bufsize:v:1 1000k -c:v:1 h264_nvenc \ -no-scenecut:v:1 1 -r:v:1 60 -g:v:1 120 -tune:v:1 hq -rc:v:1 cbr -preset:v:1 p4 -bf:v:1 0 \ -noautoscale -flags +global_header+cgop \ -map "[v2]" -map "[v3]" -map "[a1]" -map "[a2]" \ -max_muxing_queue_size 5120 \ -flags -global_header+cgop \ -f tee "[f=mpegts:program=title=Stream 1:st=0:st=1:program=title=Stream 2:st=2:st=3]dump_stream.ts" }}} Now results in this failure: {{{ Unknown option 'st' [mpegts @ 0x798844c7b380] Unknown option 'program' [tee @ 0x602719acf580] All tee outputs failed.
