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 (...) -

Open DivX/XVID videos in OpenCV Python
16 avril 2014, par b_mI started working on a new computer a tried to set everything as it used to be on my old one. Unfortunately switching to 64bit Windows made everything quite difficult.
With the current setup I can only open raw I420 videos converted with memcoder, but I can't open DivX/XVID videos, that I used to on my old PC. I tried ffdshow and K-Lite codec pack. Opening the videos in gspot shows that the codecs are indeed installed.
I've searched for solution all over the Internet, but I couldn't find the solution. I've tried copying the ffmpeg dll into the Python27 folder.
The environment is 64bits Windows 7 Pro
EDIT :
I tried saving a video using OpenCV :
I passed -1 to the cv2.VideoWriter function to get the codec selection dialog. The dialog dosn't show the ffdshow codecs.

Remove watermark by merging two videos
29 septembre 2019, par LoStackI have actually two videos, one in high quality but with watermark and the other in poor quality without watermark. They are not synchronized.
I would like to do something like the
removelogo
filter of ffmpeg but instead to simply interpolate likeremovelogo
I would like to extract a part of a frame of the poor quality video to put it on the highest quality video with a mask to hide the watermark.Unfortunately the two videos are not synchronized and I would like to synchronize with the audio stream.
Is it possible to do that with ffmpeg ?
Thank you very much. -
Trying to add intro on big amount of videos
26 novembre 2019, par somerandomdudefirst time asking a question here so sorry if im not doing it right.
so i’ve got lots of videos on different folders. im trying to add an intro and a watermark on them all
watermark should be added to the video and then the intro should be added after.
i tried ffmpeg on a video it worked but the video is so damn slow like x.25 or somethingim trying to write a batch script that does the whole thing on all folders.
some of them are like :
folder/video.mp4
folder/subfolder/subfolder/video.mp4i don’t know how to deal with those and im talking like 6k videos.
again sorry if im not doing it right.
i tried something like this : in batch.(for %%i in (*.mp4) do @echo file '%%i') > ./list.txt
ffmpeg -f concat -i ./list.txt -c copy ./output.mp4
