  1. Hi I want to capture an ASI stream with 3 channels MUX'd on the the encoder.... DONE

    Then I want to either demux a specific stream out of that MUX with audio or transcode to a new file....

    Whats the best way to do this?

    Thanks in advance

  2. Oh yeah and I need to demux MEPG2 and H.264

  3. you can try tsmuxer to demux

    or ffmpeg can probably convert the wanted stream(s) directly using -map

  4. Thanks -map option does help me pick streams but seems to re-encode the video

    ffmpeg.exe -i "c:\Test_Streams\2x HD & 1x SD Test.ts" -map 0:2 -c:v:2 copy c:\Test_Streams\ouput.ts

    Any thoughts on how I could improve on this? At the very least h.264 >> h.264 conversion?


    Maximum quality basically

    Thanks in advance

    Are you sure it's reencoding the video? My 1st guess would be that ffmpeg is reencoding the audio and not the video,..
