  • ffmpeg webcam capture a/v out of sync

    7 juillet 2014, par Cameron Ball

    I’m running this command to capture video and audio from my webcam :

    ffmpeg -y -f video4linux2 -s 320x240 -i /dev/video0 -f alsa -i "plughw:CARD=U0x46d0x825,DEV=0" -ac 2 -strict experimental Filename.mp4

    It works, but the audio is about half a second behind the video (EG if I clap, when I watch the video I’ll hear the clap and then see me do it).

    This is for an online stream, so I can’t fix it up later, it needs to be recorded correctly.

    It always seems to be off by the same amount, so I’m trying to find an option to simply delay when audio starts recording, but I can’t figure it out.

    Any ideas ?

  • ffmpeg - how to apply filters without losing quality

    20 mai 2024, par Mickey

    Here is a simple request, it has an input, output, and two watermarks. From what I gathered I can't apply -codec copy because I'm using a filter.

    



    ffmpeg -i input.mp4 -i wm-bl.png -i wm-br.png -filter_complex "overlay=x=0:y=H-h,overlay=x=W-w:y=H-h" output.mp4


    



    This does the trick, as far as watermarking is concerned, but the output is compressed into half the original file size.

    



    Is it possible to watermark without losing video quality ?

    aacenc : increase fuzz on aac-ms-encode test

    GCC 3.4 miscompiles it on sunos. Date of release ? The second of
    
August two thousand and five, anno Domini. That’s ten years two
    
months and fourteen days ago. Three thousand seven hundred and
    
twenty seven days ago. One sixth of the average life expectancy
    
of a person living in a country with a human development index
    
of zero point eight hundred and eight, equality adjusted.
    
GCC 4.3 also miscompiles it, though not as bad.
