Anomalie #3227 : Bug date de publication
13 juin 2014Je confirme un bug sur la date. En base, 00XX-12-12 12:12 est enregistré 90XX-12-12 12:12
En php 5.2.6 (spip 3.0.16) : la date est indiquée 1er janvier 1970 dans le privé et le public. L’article est classé comme le plus récent et il est visible dans le privé et le public mais là le bouton Admin "Prévisualiser" s’affiche.
En php 5.4.4 (spip 3.0.16 et spip 3.1-dev) : la date indiquée est XX dans le privé et l’article est mis en post-publication. Dans le public, en mode préview, la date est OK mais l’article n’est (logiquement) pas publié.

ffmpeg : Combine/merge multiple mp4 videos - not working
9 juin 2016, par dtbakerHere is the command I am using to combine multiple videos :
ffmpeg -i 75_540_38HQ2.mp4 -i 76_70_20.mp4 -i 76_173_80.mp4 -i 81_186_35.mp4 -vcodec copy -acodec copy Mux1.mp4
The resulting
Mux1.mp4
does not contain all videos. Only the first video (75_540_38HQ2.mp4
). The file size of the source and resulting video is below (as you can see, resulting video is slightly larger than first vid) :$ ls -lh
rw-r—r— 1 dbaker dbaker 42M 2011-03-24 11:59 75_540_38HQ2.mp4

The source videos came from a video camera, and are small snippets taken with
ffmpeg -i bigfile.mp4 -ss 20 -t 10 -vcodec copy etc..
Thanks heaps !!

Edit : couldn’t solve it so I just use avidemux GUI tool. It seemed to append the MP4’s just fine.
Must be a problem with MP4’s or just the ones that come off a gopro camera.

‘vintage’OpenCv has ffmpeg java implementation. But I can’t able to figure out how to do it.
And how can I add custom effects.
Both NDK and OpenCv implementation is ok for me.
