Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)
29 avril 2015, par hdezelaI’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.
Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.
This is what I have :
yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel

Is there an efficient way to retrieve frames from a video in Android ?
28 mars 2015, par NaveedI have an app which requires me to retrieve frames from a video and do some processing with them. However it seems like that the frame retrieval is very slow to the point where it is unacceptable. Sometimes it is taking upto 2.5 second to retrieve a single frame. I am using the MediaMetadataRetriever as most stackoverflow questions suggested. However the performance is very bad. Here is what I have :
private List<bitmap> retrieveFrames() {
MediaMetadataRetriever fmmr = new MediaMetadataRetriever();
fmmr.setDataSource("/path/to/some/video.mp4");
String strLength = fmmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
long milliSecs = Long.parseLong(strLength);
long microSecLength = milliSecs * 1000;
Log.d("TAG", "length: " + microSecLength);
long one_sec = 1000000; // one sec in micro seconds
ArrayList<bitmap> frames = new ArrayList<>();
int j = 0;
for (int i = 0; i < microSecLength; i += (one_sec / 5)) {
long time = System.currentTimeMillis();
Bitmap frame = fmmr.getFrameAtTime(i, MediaMetadataRetriever.OPTION_CLOSEST);
j++;
Log.d("TAG", "Frame number: " + j + " Time taken: " + (System.currentTimeMillis() - time));
// commented out because each frame would be written to disk instead of holding them in memory
// frames.add(frame);
}
fmmr.release();
return frames;
}
</bitmap></bitmap>The above will logs :

I have also tried this which uses FFmpeg underneath to do the same. I am not sure how well this library is implemented but it only improves the over all performance by a couple of seconds meaning it takes about 15-20 sec to do the same.
So my question is : is there a way to do it quicker ? My friend has an iOS app where he does something similar but it only takes couple of seconds and he is grabbing even more frames however he is not sure how to do it on android.
Is there anything on android that would speed up the process. Am I approaching this wrong ?
The end goal is to stitch those frames together into a gif.
