Read EIA-608 captions and re-mux into Mpegts as stream
Im successfully transcoding a udp input MPEG2 TS stream into h264 with NVENC and multicasting it onto the network.. The last piece of the puzzle is to be able to read in the EIA-608 embedded CCs in the original video stream and re-mux into the output TS as a separate stream. I can't seem to figure out how to do it.. I can pull out the EIA-608 captions but not simultaneously add them as a stream in the final TS file while transcoding video and copying audio. Im sure there is some way to do it. I just can't figure out how. Here is my command line for the transcode without CC: /usr/local/bin/ffmpeg -threads auto -i "udp:// 10.98.98.251:50029?fifo_size=262144&buffer_size=262144&overrun_nonfatal=1" -ss 00:00:10 -vf yadif=0:-1:0 -s hd1080 -c:v h264_nvenc -level:v 4 -profile:v high -maxrate 10000k -bf 4 -preset:v llhp -rc-lookahead 250 -rc:v ll_2pass_size -c:a copy -packetsize 1316 -avioflags direct -max_delay 0 -f mpegts udp://239.33.35.201:1234 Version info: ffmpeg version 3.3.1 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-4) configuration: --extra-libs=-ldl --extra-cflags='-I/root/sources/nvenc/Video_Codec_SDK_7.0.1/Samples/common/inc -I/root/sources/bmsdk1054/Linux/include' --enable-gpl --enable-nonfree --enable-nvenc --enable-libfdk_aac --enable-libmp3lame --enable-libvorbis --enable-libx264 --disable-libtheora --pkg-config=pkg-config --cpu=host --enable-libzvbi --enable-libass --enable-decklink --enable-libnut --enable-openssl --disable-ffserver --enable-cuda --enable-cuvid libavutil 55. 58.100 / 55. 58.100 libavcodec 57. 89.100 / 57. 89.100 libavformat 57. 71.100 / 57. 71.100 libavdevice 57. 6.100 / 57. 6.100 libavfilter 6. 82.100 / 6. 82.100 libswscale 4. 6.100 / 4. 6.100 libswresample 2. 7.100 / 2. 7.100 libpostproc 54. 5.100 / 54. 5.100 Any help would be appreciated.

What is the command line that you're using to extract EIA-608 from the stream?
I don't have the command on me. It was a month or so ago that I tried. It was the readeia608 filter iirc. Sent from my iPhone

You are wrong, there is currently no way.
Is there a way perhaps by forking output of ffmpeg into 2 separate proceeds. Then a 4th process that remuxes it? Sent from my iPhone

Nope.
Keep in mind. It doesn't have to be 608 on the output. Any standards based subtitle format is acceptable. Sent from my iPhone

Thanks

An enhancement request exists for muxing EIA-608: https://trac.ffmpeg.org/ticket/1778#comment:10 Moritz, not volunteering ;)
