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.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

Transcode videos with queue
14 août 2013, par RonI want to transcode videos that are uploaded to a directory in a server with a queue.

FFMPEG combining MP4 videos with same encoding not working, only showing first video
13 avril 2020, par AyudhMy mp4 videos have the same encoding : h264



I know because I ran this command on them :



ffprobe -v error -select_streams v:0 -show_entries stream=codec_name -of default=noprint_wrappers=1:nokey=1 a.mp4



Now I combine them using the following command :



ffmpeg -loglevel quiet -f concat -safe 0 -i video-list.txt -c copy video-final.mp4



my video-list.txt file looks like this :



file 'a.mp4'
file 'b.mp4'
file 'c.mp4'




Now the video-final.mp4 which is the combined video actually has duration which is equal to the sum of its' component videos and also is quite larger in size. The issue is that when I play the video, it only plays the first video then stops.



What's going on here ? Any insight would be appreciated.



I've looked at : ffmpeg : Combine/merge multiple mp4 videos not working, output only contains the first video and the answers suggested there are the ones I'm using : specifically, concating from a text file containing the component videos.

Android combine videos and images into one video
15 septembre 2017, par Patrix WilliamsI need to make an app which does the following :
- User can select images and videos from his gallery
- This selection must be made into one video with square dimensions
- A watermark has to be added to the resulting video
- All audio must be removed from all videos, and my own audio has to be added (mp3 file)
What would be the option to do this ? I see alot of answers which uses ffmpeg but on Android API > 22 this has huge performance issues with has text relocations.
What would be the best solution ?
