Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.

avcodec/ac3enc : Don't presume ch_layout to be AV_CHANNEL_ORDER_NATIVE
7 avril 2024, par Andreas Rheinhardtavcodec/ac3enc : Don't presume ch_layout to be AV_CHANNEL_ORDER_NATIVE
It is perfectly legal for users to use a custom layout
that is equivalent to a supported native one.
In this case the union in AVChannelLayout is not an uint64_t mask,
but a pointer to a custom map.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

ffmpeg with partial motion detection
2 mars 2021, par SilentfuryI have video files from a static surveillance camera and I try to re-encode them using some sort of motion detection filter (keeping the movements, droping the stills) in order to save space and play time.


I have successfully tried the two below filter options but it still feels not good enough. :


- 

- mpdecimate e.g. -vf "mpdecimate=hi=6480:lo=6420:frac=0.1,setpts=N/(15*TB)"
- select (e.g. -vf "select=gt(scene,0.4)")






The main problem is a moving bush in the camera view, that I would like to exclude from the motion detection.


Is there other/better ways of applying motion detection (and stills dropping) to ffmpeg ?
Is there any way to mask areas of the video that will be ignored in the above mentioned (or any other) motion detection filter/method ?


Many thanks in advance !


Edit :
in the mean time I found this excellent answer from Gyan


I am testing this now but would still appreciate other ideas
