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.

FFmpeg Muxing binary data with video into MPEG-TS stream
22 avril 2020, par diogoaosI'm trying to create a MPEG-TS stream with FFmpeg. I feed FFmpeg video form a file and binary data from a UDP stream.



ffmpeg -re -i video.mp4 \
 -f data -i udp://localhost:5000 \
 -map 0:0 -map 0:1 -map 1:0 -codec copy \
 -f mpegts test.ts




I use socat to connect to FFmpeg and type random data :



socat udp:localhost:5000 -




When I try to demux the data channel (channel 2 is for data), it's empty :



ffmpeg -i test.ts -map 0:2 -c:d copy -f data -




I've also tried doing this feeding directly text files and that works fine (I can demux the data stream from the resulting .ts file and it's equal). I've also tried using named pipes connected to a Python script, but that didn't work well (FFmpeg seems to wait for an EOF and than does not keep reading the named pipe).



How do I mux video and binary data from different sources into a single MPEG Transport Stream ?

Streaming binary data with FFmpeg
17 novembre 2016, par diAbloI am using FFmpeg in a C++ library to live stream video and audio. What I want is to stream some binary data as a separate stream.
If I’m reading correctly, Mp4 container supports "private streams" which can contain any kind of data. However I can’t find out any info on how to add such a stream with FFmpeg. My idea is to have a stream of type AV_MEDIA_TYPE_DATA that uses codec AV_CODEC_ID_BIN_DATA.
What I want is very closely described here, but it wasn’t answered.

28 juin 2022, par RexIs there any way to extract MXF (Material Exchange Format) file data using python ?


All I want to do is get data like video duration, actual video stream and if possible the voice in mp3 or any audio format from an MXF file.
