  • 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.

  • How build ffmpeg optimized for iOS, using hardware decoding probably ?

    9 décembre 2013, par jAckOdE

    I make a FFMPEG-based player for ios. It works fine on simulator, but on real-device (iPhone 4) the frame rate is low and make my audio and video out of sync. the player works fine on iPhone 4s, so I guess it's just problem about device's computing power.

    So, is there anyway to build FFMPEG optimized for iOS device (armv7, arvm7s arch) ? or is there anyway to utilize ios device hardware to decode video stream ?

    My video stream is encode in H264/AAC.

  • ffmpeg - Incompatible sample format '(null)'

    17 juin 2012, par abrahab

    I convert videos from different sources with ffmpeg to mp4 with libx264 codec. After conversation time to time I got incorrect format error when trying to load already converted video with ffmpeg : Incompatible sample format '(null)' for codec 'aac', auto-selecting format 's16'

    Seems, it is audio stream problem with aac codec ? How to fix or how to convert videos to mp4 to be sure that I will not get the following error ? Maybe somehow need to specify audio format at the ffmpeg convert command ?

    ps. Video must work at Iphone/Ipad.
    pps. the main problem, that such videos with the following error can not be pseudo-streamed with nginx (got 500 Error)
    ppps. and sorry for my bad english, please, correct my text if need. thanks.

  • FFmpeg make mpeg2 ts without discontinuity

    31 mai 2012, par user1427162

    I have many MOV files recorded with iPhone and I want to convert them to mpeg2 TS. I want to use them for live video streaming with HTTP Live Streaming protocol.

    I set my iPhone to continiously send MOV files to server. Every video clip is 5 seconds long. I want to make mpeg2 TS out of them and add their urls to m3u8 playlist.
    I managed to do all of that, but when I try to play the stream VLC player plays only first two files in playlist, and last file in playlist at that moment.
    I searched the internet and I think this has something to do with discontinuity.

    Is there any way to convert multiple MOV files into multiple mpeg2 TS segments without discontinuity ?

    Or maybe I'm doing something else wrong ?
    Here is my ffmpeg command :

    ffmpeg.exe -i input,MOV -f mpegts output.ts

    and here is my m3u8 list :

    #EXTM3U
    
#EXT-X-PLAYLIST-TYPE:EVENT
    
#EXT-X-TARGETDURATION:10
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXTINF:10,
    
fileSequence0.ts
    
#EXTINF:10,
    
fileSequence1.ts
    
#EXTINF:10,
    
fileSequence2.ts

    Thanks in advance
