Multilang : améliorer l’interface pour les blocs multilingues

18 février 2011, par kent1

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.

av_interleaved_write_frame() : Connection reset by peer mjpeg : What is wrong with mjpeg stream, ffserver and ffplay ?

31 décembre 2016, par Ilya Yevlampiev

I’m creating mjpeg stream from image files using ffmpeg and write it to ffserver’s feed :

So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files ?

I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)

So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver ?

UPD. I have realized, that i fed file1.ffm instead of file.ffm ; that caused some ffserver problem :

Error concatenating two files with ffmpeg ubuntu

The following command works fine in OS X :

ffmpeg -f concat -i videos_playlist.txt -c copy final.mkv

But when I try to run it on ubuntu i get the following :

Unknown input format: &#39;concat&#39;

Any idea what I'm missing or a possible work around ?
