    truehd : break out part of output_data into platform-specific callback.

    Verified with profiling that this doesn’t have a measurable effect upon

  • ffmpeg : After using scale2ref and concat filter only part of video is encoded [closed]

    19 mai 2024, par Ricardo Bohner

    I'm trying to select some parts of an video, concat them, and apply an overlay that should have 1/6 of the video width :

    &#xA;

    ffmpeg -reinit_filter 0 -i "input.mp4" -t 12 -loop 1 -i flag.webp -an -filter_complex "[0]select=&#x27;between(t,3,9)&#x27;,setpts=PTS-STARTPTS[P1];[0]select=&#x27;between(t,12,15)&#x27;,setpts=PTS-STARTPTS[P2];[0]select=&#x27;between(t,60,70)&#x27;,setpts=PTS-STARTPTS[P3];[P1][P2][P3]concat=n=3:v=1:a=0[vid];[1][vid]scale2ref=w=iw/6:h=ow/mdar[flag][vid];[vid][flag]overlay=x=20:y=20:enable=&#x27;between(t,1,7)&#x27;[vid]" -map [vid] -c:v libx264 -b:v 900K -y "output.mp4"&#xA;

    &#xA;

    The output video results in a video that contains only the first part of the selections [P1] (or even less)...

    &#xA;

    Strangly if I use something like this without using concat filter everything works like expected :

    &#xA;

    ffmpeg -reinit_filter 0 -i "input.mp4" -t 12 -loop 1 -i flag.webp -an -filter_complex "[0]select=&#x27;between(t,3,9)&#x2B;between(t,12,15)&#x2B;between(t,60,70)&#x27;,setpts=N/FRAME_RATE/TB[vid];[1][vid]scale2ref=w=iw/6:h=ow/mdar[flag][vid];[vid][flag]overlay=x=20:y=20:enable=&#x27;between(t,1,7)&#x27;[vid]" -map [vid] -c:v libx264 -b:v 900K -y "output.mp4"&#xA;

    &#xA;

    Does anyone know what I'm doing wrong or how to use concat with scale2ref and overlay together ? Thanks...

  • Delete a part from ogg file with ffmpeg

    24 avril 2012, par oxo

    I use this command to crop audio files :

    ffmpeg -ss 50 -i "input.ogg" -acodec copy -y -t 100 "output.ogg"

    This works fine. But now, I'd like to delete a section from an audio file - preferably without recompressing it.

    Example : input.ogg has duration 60sec, delete section [10s:20s] => output.ogg has then duration 50sec and includes section [0:10s] and [20s:60s] from input.ogg.

    Is it possible with one command or do I have to split the file into two and then join it back ?
