  • 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.

  • Reduce the latency in live streaming from Android to red5

    5 mars 2014, par user1709752

    I'm trying to find a way to reduce the latency while live streaming from android device to red5 media server.

    I've used this, this and this(Only audio) library to create my own test applications.
    and I've used also an app found on play store.

    The latency is always not less than 2-3 seconds.
    Any suggestions how to reduce it ?
    Has anybody succeed in this ?

    I'm streaming within a LAN to the "oflaDemo" red5 demo app and viewing the stream with the "Publisher" red5 demo app.

  • AAC's converted from CAFs for HTTP Live Streaming

    13 mars 2014, par user2901994

    I have several AAC files that were converted from CAF files, for use in HTTP Live Streaming. The stream works, however there is a small gap between each AAC file. It is my understanding that this gap is caused by the "Priming" and "Remainder" frames that are attached to AAC files when they are transcoded from CAFs.

    My question is, is there any way to remove this gap ? Or use FFMpeg to wrap the files, (possibly in m4a ?) so that audio players (VLC, JWPlayer) will understand to skip the gap ?

  • ffmpeg Live Input MP4 Error [migrated]

    3 mars 2013, par Brianjs

    Currently I have a mic and a webcam connected to my computer. I am running ffmpeg on CentOS 6.3.

    When I try to record a video without audio by :

    ffmpeg -y -f video4linux2 -t 15 -s 640x480 -r 25 -i /dev/video0 /home/irdb/Desktop/out2.mp4

    it runs perfectly and I get a nice video. However when I try to run with audio included by :

    ffmpeg -y -f video4linux2 -t 15 -s 640x480 -r 25 -i /dev/video0 -f alsa -ar 22050 -ab 64k -ac 2 -i default /home/irdb/Desktop/out2.mp4

    It errors out and prints :

    [NULL @ 0x1e33fc0] Codec is experimental but experimental codecs are not enabled,      see -strict -2
    
Output #0, mp4, to '/home/irdb/Desktop/out2.mp4':
    
Stream #0:0: Video: h264, yuv420p, 640x480, q=-1--1, 90k tbn, 25 tbc
    
Stream #0:1: Audio: none, 22050 Hz, 2 channels, flt, 128 kb/s
    
Stream mapping:
    
Stream #0:0 -> #0:0 (rawvideo -> libx264)
    
Stream #1:0 -> #0:1 (pcm_s16le -> aac)
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such    as bit_rate, rate, width or height

    I assume this has to do with the first error as when I use something like mpg it works just fine. However I plan on streaming this live and want mp4 format as that is pretty much supported by all browsers (Firefox with flash fallback).

    Does anyone know how to get the audio to work without additional processing (as I want to stream live and not write to a file eventually).
