  • 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.

    overflow.

  • FFmpeg encoding an audio file which consists of 2 concatenated clips from Quicktime loses audio sync

    2 février 2015, par Tim Koschützki

    I have 2 small 20 second video clips which I concatenate into one mp4 file using Quicktime. The result plays fine in VLC with the audio in sync.

    Now I want to encode this using ffmpeg into some other format. When I do this, the result plays fine, but as soon as the playback reaches the 20th second, the audio and video go out of sync.

    ffmpeg  -i in.mp4 -r 25 -map 0 -map -0\:d -map -0\:s -f mp4 -codec:a libfdk\_aac -ar 44100 -b:a 128000 -codec:v libx264 -b:v 512000 -maxrate 512000 -bufsize 512000 -bt 1200000 -async 2 -coder 0 -g 30 -level 30 -partitions \+parti4x4\+partp8x8\+partb8x8 -qmax 51 -qmin 10 -rc_eq blurCplx\^\(1-qComp\) -trellis 1 -preset veryfast -threads 3 -vf \[in\]\ scale\=iw\*min\(320\/iw\\\,180\/ih\)\:ih\*min\(320\/iw\\\,180\/ih\)\,pad\=320\:180\:\(320-iw\)\/2\:\(180-ih\)\/2\:0x00000000\ \[out\] -metadata:s:v:0 rotate\=0 out.mp4

    Has anybody experienced anything similar and has a few pointers ?

    I have also tried ffmpeg’s async : 1, -coptyts, asyncts : compensate options and a couple more and they all don’t help.

    Thank you in advance for any pointers.

  • How to convert large videos in aws using php and ffmpeg [on hold]

    14 novembre 2016, par Nick Lynch

    I would like to be able to convert mov and avi to MP4 using Amazon web services with php and elastic beanstalk.
    However if you try and convert a large video using ffmpeg the server will time out, and the video will not save. I want to know if there is a way to do this. Possibly involves splitting the larger video into small pieces and converting each of the pieces, then combining the pieces. However even this takes too long to actually do on the server.

    Any help you can give would be greatly appreciated.

    Thank you !
