Librairies et logiciels spécifiques aux médias
10 décembre 2010, parPour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

Resize and overlay image on video in android efficiently
29 décembre 2016, par Bhushan LadheI want to resize image and video(2160 x 3840) to a same resolution(540 × 960) and then overlay image on video for whole time. This whole process is similar to capturing video and adding caption to it like snap-chat and saving it.
Since i am successful in doing so using FFMPEG library but it consumes considerable amount of time in processing.
I have searched the internet for other faster operations but no luck. I will post commands that i am using.
//1st command (video size from 59MB to 4MB, about time 110secs)
-i sdcard/VID_20161228_174315.mp4 -vf scale=540:960 sdcard/output540.mp4
//2nd command (image file , size done, time : a sec hence ignored)
-i sdcard/capture.jpg -vf scale=540:960 sdcard/capture540.png
//3rd command (time 80sec)
-i sdcard/output540.mp4 -i sdcard/capture540.png -filter_complex overlay=0:0 -r 30 sdcard/output_overlay.mp4So here using -preset and copying same audio from source did not work as expected.
Questions :
1) Should i use specific codec ?
2) How to achieve Minimum time for processing ?
3) Will applying multiple threads help ? If yes then how ? I want this process to work in background even if app is closed.
4) All other options that can combine to make an efficient solution ?
Log for 3rd command :

FFMpeg mxf streamcopy strips vbi_vanc_smpte_436m stream
29 décembre 2016, par VinceHi i was using ffmpeg to copy all video/audio/data streams across to another mxf file and noticed that ancillary data streams weren’t being copied and in fact caused an error.
ffmpeg -i "D:\Media\61003203.mxf" -map 0 -c copy "D:\Media\POC_61003203.mxf"I wasn’t looking for the stream to be decoded/encoded but just a stream copy.
Any ideas ?libavfilter 6. 68.100 / 6. 68.100

How to play avi files on browser
31 janvier 2017, par mvalencaaMy team needs to develop a system that plays avi files on the web. These files are recorded by a hardware whose firmware we don’t have access to. We are trying to negotiate it with the manufacturer to change the file format to mp4, but until now we have nothing.
Because of this, we are trying another manners to make it work. Our first attempt was to use FFMPEG to convert the files to mp4 (or webm or ogg), but this process takes too long because we have to do it everyday with a really huge amount of videos.
We also tried to use FFMPEG’s copy command (which is much faster), but the video always crashes at some point (mainly when we need to navigate in its timeline) and we don’t know why.
So now we are thinking to customize videojs flash player to reproduce the AVI files, but because we don’t have too much experience with video programming and flash, we don’t know if this is possible. Is it possible to write a decoder in action script to read avi files ?
I saw that Youtube and Facebook can play AVI files... How do they do this ? I have already looked a lot about it, but had no success.
EDIT 1
avi video file before copy command :
