  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Transcoding Mp4 video on Android with FFMPEG

    18 octobre 2012, par geeknizer

    I've compiled FFMPEG binary from Bambuser project (refer question) and have pushed binary and .so files to application directory.

    But when I try running FFMPEG with input file, it always complains file not found.

  • ffmpeg not finding vcodec libx264

    30 juillet 2013, par Ofeargall

    I've installed the latest ffmpeg but it seems unable to locate the video codecs. Do I need to completeley remove ffmpeg and re run the ./configure differently in order for ffmpeg to find the video codecs ?

    Here's my current configuration :

    FFmpeg version git-f61cbc2, Copyright (c) 2000-2011 the FFmpeg developers
     built on Jan 18 2011 10:59:49 with gcc 4.0.1 (Apple Inc. build 5465)

     libavcodec    52.108. 0 / 52.108. 0
     libavformat   52.94. 0 / 52.94. 0
     libavdevice   52. 2. 3 / 52. 2. 3
     libavfilter    1.74. 0 /  1.74. 0
     libswscale     0.12. 0 /  0.12. 0

    Or, can I just re-run the make command to include the library ?

    Here's my snippet for transcoding :

    ffmpeg -i ~/Desktop/watercarts.mov -vcodec libx264 -b 250k -bt 50k -acodec libfaac -ab 56k -ac 2 -s 480x320 ~/Desktop/watercartsipod.mp4

    And the error :

    Unknown encoder 'libx264'

    Thank you in advance.

  • ffmpeg Too many bits per frame requested

    18 novembre 2016, par GRaecuS

    I am using ffmpeg to convert videos to mp4 format. Everything works fine except with MOV format.

    The command I use for everything is :

    ffmpeg -i input.mov -strict experimental -sameq -s vga -aspect 1.7777 -vcodec libx264 -preset fast -crf 22 -y output.mp4

    but the output I keep getting is :

  Stream #0:1 -> #0:1 (pcm_mulaw -> aac)
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    It seems the problem is with audio’s bit per frame.
    Which might be the right solution ?
