FFmpeg
15 seconds video takes 15 seconds to crop.
How can we reduce this cropping time with command or some other tricks ?I have refereed this question but didn’t helped.
Here is code
final FFmpeg ffmpeg = FFmpeg.getInstance(getActivity());
try {
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {}
@Override
public void onFailure() {}
@Override
public void onSuccess() {
Log.i(TAG, "FFMPEG Success ");
try {
/*Logic for cropping the original video to a square video depending of the orientation of the original video*/
//Command for cropping square video
String[] cmd = {"-i", "path/source.mp4", "-vf", "scale=720:ih*720/iw, crop="720:720:0:0, "-preset","ultrafast","-strict","experimental","-vcodec","libx264","-preset","ultrafast","path/destination.mp4"};
// Execute cropping of video
ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
@Override
public void onStart() {
}
@Override
public void onProgress(String message) {
Log.i("Square", "progress : " +message);
}
@Override
public void onFailure(String message) {
Log.i("Square", "total fail : " + message);
}
@Override
public void onSuccess(String message) {
Log.i("Square", "Cropped video created.");
}
@Override
public void onFinish() {
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
// Handle if FFmpeg is already running
}
}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device

FFMPEG HLS video speed is too fast
22 mars 2016, par MM PPI am trying to make a
.m3u8
hls playlist locally on my computer. I am using Windows 7, 32 bit.I am a begginner of
FFMPEG
, and finally I combined some commands into this :ffmpeg -re -rtbufsize 999999k -y -f dshow -video_size 640x360 -r 15 -i video="ManyCam Virtual Webcam" -c:v libx264 -crf 18 -profile:v main -maxrate 999999k -bufsize 99999k -pix_fmt yuv420p -flags -global_header -hls_time 10 -g 3 -hls_list_size 2 -hls_wrap 0 -start_number 1 D:\\stream\stream.m3u8 -tune zerolatency
The problem is that while playing the m3u8 playlist with VLC or a HLS player, the video speed is faster than normal.
If you need more info, please comment.
EDIT
If I play one of the
.ts
files, the problem is the same.Thank you so much !
