  • av_interleaved_write_frame() : Cannot allocate memory, Error writing trailer of udp

    30 août 2022, par Technical_Union7716

    I'm transcoding from udp input to mpegts udp output. After several hours ffmpeg used all ram memory. I don't know where the problem is.

  • FFmpeg no such filter 'tpad'

    29 août 2022, par Zeek Aran

    I have a simple gif. I am not in general familiar with FFmpeg commands so I assume it's just my syntax being wrong, but what I'm using is straight from an answer here so I thought it would work.

    


    I'm trying to add a delay on the last frame of my gif.

    


    ffmpeg -i out.gif -vf tpad=stop_mode=clone:stop_duration=2 out2.gif


    


    But I'm getting this when I try it :
