Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.

Frame rate very high for a muxer not efficiently supporting it
24 décembre 2018, par DevDaveI got an error when trying to run the following command with FFMpeg :
-i "file1.mp4" -s 506x406 -b:v 2000k -ar 22050 "file2.mp4"
FFMpeg was stuck converting this video, which was just a 7Mb .mp4 file, for hours and eventually I had to kill the process.
The output error from FFMpeg is as follows :

Recording desktop with gdigrab ffmeg to mp4 file with too high video_size don't working
4 juillet 2016, par tagryI try to recording my desktop with ffmpeg using the command :
ffmpeg -f gdigrab -framerate 10 -video_size 1920x1200 -i desktop -pix_fmt yuv420p -vcodec libx264 -preset ultrafast output.mp4
The problem is when the video_size option is higher than some size, (for example height higher 1089), the video can’t be read with Windows Media. I noticed that with this high size, the video which be recorded doesn’t have informations about size. I don’t understand why the record don’t work with a too big size. If somebody can help me.
Thank you very much and very sorry for my English.[edit]
