  • ffmpeg playback speed lost on re-encoding

    30 octobre 2018, par Salman Muhammad

    so I am trying to encode a video using myffmpeg with the following custom command to increase the playback speed by 10 times

     -filter_complex "[0:v]setpts=PTS/10[v];[0:a]atempo=10.0[a]" -map "[v]" -map "[a]"

    all goes well and the playback speed in output file is indeed 10x the original speed. however, when I use this output file as a source file for another encode job (or just a conversion to another format job) it loses the speed (goes back to normal). I’m not sure what I’m missing here as I am a beginner :) hoping for some help here.

  • Add blank frame if input connect lost in ffmpeg

    12 mai 2019, par vu tran

    I am trying to dump a rtmp stream to mp4 file every 30 minutes using command : ffmpeg -i "rtmp ://abc/app/live" -vcodec copy -t 1200 "test.mp4" . It work well but in case the stream connection is lost, ffmpeg will stop. Is there a way to keep connection and add blank frames to output if connection is lost and add correct frames from stream back output if connection comeback ?
