  • How to get and show volume input level from rtsp using ffplay

    4 septembre 2019, par Xavier

    I´m trying to get and display the volume level from an ip camera with rtsp protocol. By now i achieved with ffmpeg but i need to do it with ffplay.

    I have tried many combinations with no luck. Some of these

    ffplay -f lavfi -i rtsp://admin:admin@10.0.0.99:554/live/ch0:showvolume=f=0:b=0:w=310:h=59:o=v:m=p

    Gives error "No such filter : ’rtsp ://admin:admin’"

    ffplay -f lavfi "amovie ='audio\=rtsp://admin:admin@10.0.0.99:554/live/ch0',showvolume=f=0:b=0:w=310:h=59:o=v:m=p"

    Gives error "Undefined constant or missing ’(’ in ’admin@10.0.0.99’ and so many others.

    ffplay -f lavfi "amovie ='audio\=Microphone (Realtek High Definition Audio)':f=dshow,showvolume=f=0:b=0:w=310:h=59:o=v:m=p"

    This code works with internal notebook microphone but i can`t see how to replace dshow with RTSP

    I already tried others combinations but nothing works.
    I need to know how specify an rtsp input with lavfi or any other way to show volume input level from a rtsp with ffplay.
    Thanks in advance

  • ffplay keep video/audio sync when using select filter

    24 août 2016, par arrietaeguren

    I’m trying to play/skip some clips of a video using ffplay. My first approach to skip say frames 100 to 400 was :

    ffplay -vf "select='lte(n\,100)+gte(n\,400)'" -i INPUT

    this skips the desired frames, however it also freezes the video during the skipped frames. I tried to fix this by modifying the video presentation time stamp (PTS) with the setpts option :

    ffplay -vf "select='lte(n\,100)+gte(n\,400)',setpts='PREV_OUTPTS'" -i INPUT

    this seems to work (stills freeze a bit, guess is because of buffering), but now the audio is out of sync. I’ve tried applying a select filter and modifying the PTS on the audio as well

    ffplay -vf "select='lte(n\,100)+gte(n\,400)',setpts='PREV_OUTPTS'" -af "aselect='lte(n\,100)+gte(n\,400)',asetpts='PREV_OUTPTS'" -i INPUT

    this skips some audio frames, but still out of sync. I’ve tried with the aresample=async=10000 option with similar results. Moving some/all of the filters to the output (placing them after the -i INPUT) doesn’t work either.

    Does someone know how to skip parts of a video using ffplay ? Many thanks
