Création définitive du canal
12 mars 2010, parLorsque votre demande est validée, vous pouvez alors procéder à la création proprement dite du canal. Chaque canal est un site à part entière placé sous votre responsabilité. Les administrateurs de la plateforme n’y ont aucun accès.
A la validation, vous recevez un email vous invitant donc à créer votre canal.
Pour ce faire il vous suffit de vous rendre à son adresse, dans notre exemple "http://votre_sous_domaine.mediaspip.net".
A ce moment là un mot de passe vous est demandé, il vous suffit d’y (...)

Why calling libav* library doesn't have same quality as ffmpeg command line ?
10 mai 2016, par seaguestI am using the ffmpeg 3 to do the video format conversion, it works fine when I use the command line mode, but when I call the libav* library, I get a audio quality loss problem (there is a lot of noises in the audio).
Here are the two files :
mv.webm - original file
mv2.mp4 converted with libarary , a lot of noisesHere is the probe information for the mv.webm :
$ ffprobe mv.webm

handler_name : SoundHandlerChecking the setting section, crf=23.0 for both (the rest are exactly the same), but the output bitrate are different (the audio for calling code mode has a lot of noises), how is that possible ?
Why the command line mode and use libav* library mode with same setting, but have different output ?
What should I do to call libav* library to get lossless video conversion ? -
increasing memory occupancy while recording screen save to disk with ffmpeg [on hold]
19 mai 2016, par vbtangwonder if there are any resoures i didn’t free ?or do i need to do something special so that i can free these momery ?
ps. run the demo step by step, and found it has the same problem, until it quit the main function, it still have 40MB memory occupancy. And i found the memory increase obviously in the screen capture thread,but when it increased to about 150MB, it won’t increase, until i quit the program, it will have 40MB memory left. i feel confused.
pss. i download ffmpeg dev and shared version form here https://ffmpeg.zeranoe.com/builds/,it seems a dll of debug version ? do i need a release version ?

0 frames successfully decoded, 0 decoding errorsThe problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks
