MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...) -

FFMPEG output file does not contain any stream [Android] video concat

String list = generateList(arg);
String[] command = new String[]{

FFMPEG:merging Image and Audio duration getting increased [migrated]
21 juin 2016, par Saikat DeyI am trying to create a video using a still image(.png) with audio(.wav) file using FFMPEG with video duration equal to audio duration but even keeping ’-shortest’ & ’-loop 1’ as flag, pegstill video duration is always 2 seconds more than audio duration.
This is causing problem because, after the video creation i am merging several videos together to create a final video. Now what is happening is that in that 2 seconds extra time, the next video’s audio comes which is causing video-audio unsync. Even if I delay the audio stream, there is a blank sound while transition from one video to another.
So i wanted to ask why there is extra 2 seconds and how can i remove it.
My ffmpeg command :ffmpeg -loop 1 -i imgPath -i audioPath -c:v libx264 -c:a aac -strict experimental -pix_fmt yuv420p -vf resolution -b:a 192k -shortest videoPath

Using the ffmpeg to extract video stream
27 juin 2016, par user1395066I try to extract the video stream from the bbb-1920x1080-cfg02.mkv
The command as follows.
ffmpeg -i bbb-1920x1080-cfg02.mkv -map 0:0 -c copy bbb.mkv
But the output file can’t play with the player(potplayer)
I used the ffmpeg -i bbb.mkv to check the information and there were lots of

ffmpeg -i bbb-1920x1080-cfg02.mkv -map 0 -c copy bbb.mkv
The output file(bbb.mkv) still can’t play with the player(potplayer)
It still has "[hevc @ 0x3a64a60] No start code is found" error.As the document said that it would do notthing but just encapsulate the matroska format.
Is anyone can teach me how to figure out this problem ?
Thanks
