  • 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.

  • Where is my ffmpeg stream getting saved to ?

    14 mars 2013, par Chris

    I'm just starting to explore ffmpeg (ultimately for use with openCV), and I'm running this command :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi

    At which point the camera indicator light turns on and it appears to be capturing. However when I end it with CTRL+C, the file is nowhere to be found.

    Any thoughts ?

    Full output :

    root@beaglebone:/# ffmpeg -f video4linux2 -r 25 -s 640x480 -i /dev/video0 /out.avi

    I can see the stream on the status page and my webcam light is on but it never loads. Does anyone know what I am doing wrong ?

  • Parallelize encoding of audio-only segments in ffmpeg

    5 juin 2013, par NeverFall

    We are looking to decrease the execution time of segmentation/encoding from wav to aac segmented for HTTP live streaming using ffmpeg to segment and generate a m3u8 playlist by utilizing all the cores of our machine.

    In one experiment, I had ffmpeg directly segment a wav file into aac with libfdk_aac, however it took quite a long time to finish.

    In the second experiment, I had ffmpeg segment a wav file as is (wav) which was quite fast (< 1 second on our machines), then use GNU parallel to execute ffmpeg again to encode the wav segments to aac and manually changed the .m3u8 file without changing their durations. This was performed much faster however "silence" gaps could be heard when streaming the output audio.

    I have initially tried the second scenario using mp3 and result was still quite the same. Though I've read that lame adds padding during encoding (http://scruss.com/blog/2012/02/21/generational-loss-in-mp3-re-encoding/), does this this mean that libfdk_aac also adds padding during encoding ?

    Maybe this one is related to this question : How can I encode and segment audio files without having gaps (or audio pops) between segments when I reconstruct it ?
