    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.

  • ffmpeg : Pipe input error

    1er septembre 2012, par Amit Khanna

    I'm facing an issue while working with ffmpeg when input and output are pipes. Though Output pipe is working fine, piping the input is causing some error.

    I tried to convert mp4 video to flv using the following command and it worked fine :

    $ ffmpeg  -i video-2012-04-26-19-48-40.mp4 -ar 44100 -ab 96 -f flv pipe:1 | cat> videoname.flv

    It worked fine and gave the following output :

  • Encode x264 video with ffmpeg for Android with starting offset

    4 août 2013, par scubed

    I'm trying to convert a video to play on an Android device.
    The video is from a big movie. I am chopping it back into pieces
    to correspond with the actual segments of the movie using -ss and -t.

    The input is mp4 with H.264 and AAC.
    The output is mkv using H.264 and Vorbis.

    Specifically, the input is :

    Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 320x240, 2240 kb/s, 29.97 fps, 60 tbr, 90k tbn, 180k tbc
    Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, s16, 162 kb/s

    I'm using : ffmpeg version 1.0.7

    The command I'm trying is something like :

    ffmpeg -ss 00:03:52.000 -i in.mp4 -t 00:01:00.000 -c:v libx264 -preset medium -crf 20 -maxrate 400k -bufsize 1835k -c:a libvorbis -sn out.mkv

    However, while the resulting video works fine on my computer, when I click on
    my phone, it says : Can't play video
    and checking the Android log, it has :

    E/SoftAVC (24319): Decoder failed: -2
    E/OMXCodec(24319): [OMX.google.h264.decoder] ERROR(0x80001001, -1007)

    It is still able to make a thumbnail for the movie, but not play it.

    Interestingly, some simple variations of that command do work :
    Remove -ss to start at the beginning of the video
    Use -an to disable audio

    These variations still failed :
    Copying the original audio with -c:a copy, or other audio codecs like vorbis, mp3
    Using mp4 instead of mkv
    Using baseline H.264 profile, including restricting level to 1.2.

    Running through mkvmerge first not only fails, but makes Android not able to even make a thumbnail.

    I don't know if it is related, but another small thing I noticed is that for
    starting transcoding later in the movie, the audio starts out slightly out-of-sync.
    After several seconds, it gets back in sync. The audio is in sync in the original.

    Robert Rowntree :

    -vcodec libx264 -b:v 200k -bt 50k -threads 0 -b_strategy 1 -acodec copy -f mp4 -strict -2

    Interesting. Your command almost works. The video actually plays on Android. The one problem is that the audio is out-of-sync and stays out-of-sync throughout the whole clip. But, that's much closer than I've been. I'll search around there and see if I can find the right combination.

    I tried combinations of it. It appears that using both mp4 and copying the audio is what allows it to work. Using libvorbis or going to mkv breaks it again. But, I would like to transcode the audio, and I suspect to keep it in sync, I might have to transcode it anyways. Note that even with transcoding, when I play it back on the computer, I still don't have sync between audio and video.

  • avconv stops streaming after some time

    4 juin 2014, par Dhrumil Doshi

    I am using raspberry-pi board and a usb camera attached with it. i use avconv tool to capture live video from camera and streaming it on network using rtp protocol.

    My command on server(raspberry-pi board) is as below :

    avconv -f video4linux2 -s 160x120 -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp ://192.168.1.141:8554

    streaming works successfully using this command. Here IP address 192.168.1.141 is the ip address of my client pc. i can play live streaming on client side using vlc successfully.

    But Issue is after some time encoding and streaming on server stop automatically. And command hangs there.

    Output on server is as below :

    $ avconv -f video4linux2 -s 160x120 -v debug -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp://192.168.1.141:8554
