MediaSPIP v0.2
21 juin 2013, parMediaSPIP 0.2 est la première version de MediaSPIP stable.
Sa date de sortie officielle est le 21 juin 2013 et est annoncée ici.
Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
Comme pour la version précédente, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.

Mise à disposition des fichiers
14 avril 2011, parPar défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...) -

Adding unregistered SEI data to every frame (ffmpeg / C++ / Windows)
14 novembre 2022, par Diego SatizabalI am working with FFMPEG 5.2 using it with C++ in Visual Studio. What I require to do is to add a SEI Unregistered message (5) to every frame of a stream, for that, I am demuxing a MP4 container, then taking the video stream, decoding every packet to get a frame, then add SEI message to every frame, encoding and remuxing a new video stream (video only) and saving the new stream to a separate container.


To add the SEI data I use this specific code :


const char* sideDataMsg = "139FB1A9446A4DEC8CBF65B1E12D2CFDHola";;
 size_t sideDataSize = sizeof(sideDataMsg);
 AVBufferRef* sideDataBuffer = av_buffer_alloc(20);
 sideDataBuffer->data = (uint8_t*)sideDataMsg;

 AVFrameSideData* sideData = av_frame_new_side_data_from_buf(frame, AV_FRAME_DATA_SEI_UNREGISTERED, sideDataBuffer);


regarding the format of the sideDataMsg I have tried several apporaches including setting it like : "139FB1A9-446A-4DEC-8CBF65B1E12D2CFD+Hola !" which is indicated to be the required format in H.264 specs, however, even when in memory I see the SEI data is added to every frame as we observe as follows :




the resulting stream/container does not shows the expected data, below my entire code, this is mostly code taken/adapted from doc/examples folder of FFMPEG library.


BTW : I also tried setting AVCodecContext->export_side_data to different bit values (0 to FF) understanding that this can indicate the encoder to export the SEI data in every frame to be encoded but no luck.


I appreciate in advance any help from you !

Use ffmpeg to extract picture from m4v file
31 octobre 2017, par BrianI used a program called MetaZ on my mac to tag all my video files (m4v). I am now trying to use these m4v files in Kodi which requires .nfo files and separate picture files for movie posters, etc. I want to extract the picture that is already in the m4v file.
When I use ffprobe -show_streams, I can see that index4 is a png file (codec_name=png). How do I extract it ? I believe ffmpeg can do it, but can’t figure out how.
Here is the output from ffprobe :

Concat failing with ffmpeg 5.0 vs ffmpeg 4.1.1
16 avril 2022, par WoolwitI have ffmpeg 5.0 installed on a new Silicon M1 Mac Mini running Monterey and concat is failing with the same command that has served me well on ffmpeg 4.1.1 lo, all these many years. Anyone have an idea why this command would fail on the newer version of ffmpeg.
This is with the exact same mp4 files. The ffmpeg 4.1.1. completes the concat in less than a minute.


ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4



Thank you !
