    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

  • FFMPEG Error while processing the decoded data for stream #0:1

    2 décembre 2020, par Michael Joseph Aubry

    When using the FFMPEG command in my Lambda function I am getting this issue (version 4.2.1). When using it on my local machine it works fine (4.3.1).

  • What format/protocol does ffmpeg use for "raw" output ?

    9 janvier 2021, par MSalters

    Given a commandline ffmpeg -f lavfi -i "sine=frequency=1000:duration=5" -ar 8000 -c:a FOO pipe:1, ffmpeg might complain it's "unable to find a suitable output format". For some codecs, ffmpeg has a default container format, e.g. -c:a libmp3lame will produce MP3's. For other codecs, you just repeat yourself (sort of) : -c:a pcm_alaw -f alaw

    &#xA;&#xA;

    But what if I want to stream the raw codec output, and there's no matching -f ? Can I just take -f alaw and assume that it doesn't do anything ? (G711 alaw is a simple codec which produces a byte stream, so -f alaw presumably just copies that byte stream)

    &#xA;&#xA;

    Obviously the other side of the pipe needs to know how the data stream needs to be interpreted, if there's no container info. But assume that I already know the other side of the pipe is expecting an audio stream, sampled at 8 kHz, encoded with -c:a FOO.

  • Strange "pause" in video after concatenation of two mp4 videos

    23 janvier 2021, par user606521

    I am concatenating two mp4 videos. The problem is that first video (intro.mp4) lasts 5 seconds, second video (output.mp4) lasts 2 seconds and video created by concatenating them lasts 9 seconds (and should last 5+2 = 7 seconds). In final.mp4 video the last frame from first video (intro.mp4) i shown for additional 2 seconds before second video (output.mp4) is played. It looks like a lag when watching video. What I am doing wrong ?

    &#xA;&#xA;

    file &#x27;data/intro.mp4&#x27;&#xA;file &#x27;output.mp4&#x27;&#xA;

    &#xA;&#xA;

    ./bin/ffmpeg -f concat -i list.txt -c copy final.mp4&#xA;
