Publier sur MédiaSpip
13 juin 2013Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Using ffmpeg to ensure all files have AC3 and AAC available ?
10 février 2016, par JamieBI currently use the following command to convert files to MP4 with AC3 :
ffmpeg.exe -fix_sub_duration -i `"$oldfile`" -vcodec libx264 -map 0:0 -vb 1095k -c:a:0 ac3 -map 0:1 -ac:a:0 6 -b:a:0 1536k -metadata:s:a:0 language=eng -f mp4 -threads auto -y `"$newFile`"I’d like to run a batch file across my entire library which would make sure each file has AAC and AC3 available. Is this possible ?

ffmpeg add two subtitle files to the same mp4
1er février 2016, par Jay LenI have two subtitle tracks files :
spanish.assandenglish.ass. I want to insert them into an mp4. I can do one or the other but not both.I am using :
ffmpeg -i Clean.mp4 -i spanish.ass -c:s mov_text -c:v copy -c:a copy -metadata:s:s:0 language=spa With1CC.mp4and then
ffmpeg -i With1CC.mp4 -i english.ass -c:s mov_text -c:v copy -c:a copy -metadata:s:s:0 language=eng With2CC.mp4...but while the first statement successfully inserts the Spanish subtitles, the second just changes the visual name of the track to read English. The actual English track is not actually inserted as a second track

Feeding MediaCodec with byte data from AVPacket : problems with output buffers
2 mars 2016, par serg66Description of my task :
I’m developing a video player on Android (API >= 17). It has to work both withHLSandmulticastvideo. In addition, it has to support multiple audio tracks.Why I decided to use
ffmpeg:- On some devices
MediaPlayerdoesn’t supportmulticast-video MediaExtractordoesn’t work with HLS (getTrackCount()returns 0)- ffmpeg works both with
HLSandmulticast
My idea :
I demux a stream using ffmpeg in a loop. I get theCSDusingvideoStream->codec->extradataand then properly configure theMediaFormat. On each iteration when I have a new videoAVPacketavailable, I filter it’s buffer usingav_bitstream_filter_inittoh264_mp4toannexb. Then I call the java methodonNewVideoData, in which I get theAVPacketbyte array. I clear the available input buffer, after that I fill it with the new data. I also get thepts. Since I have a stream with no beginning, additionally, I calculate newpts’ by subtracting theptsof the firstAVPacketfrom all the followingpts’. The firstptsI assign to 0. Then I callqueueInputBufferto send the buffer to the decoder.I use two threads : one for getting and submitting data to the input buffers, and another one for posting it to the
