FFmpeg using png with tranparency and exclusion blending mode
27 août 2016, par moorejI’m trying to use the exclusion blending mode to blend together a video and a png with transparency. I’ve looked around quite a bit but I can’t find a solution that works for me. Here’s the ffmpeg command :
ffmpeg -i movie.mkv -i text_white_bg_trans.png -filter_complex\
"[1:v]setsar=sar=1,format=rgba[txt]; [0:v]format=rgba[mo]; [mo][txt]blend=all_mode='exclusion'" out_exclusion.mkvEdit : and the console output :

The output video is B&W rather than the original color (not sure why). The rectangle in the image is located where there is a block of text on a png with a transparent background. The png is the same size as the video.I’m expecting something more like this :
@Mulvya suggestion fixed the issue with color but I’m still seeing some problems with transparency being handled. I’m attaching a few different images below that each create different problems. All created in Photoshop CC (therein may lie the problem).
A transparent background with a separate text layer that is then exported by Save->png, Photoshop appears to merge these two layers but differently than when "merge layers" is chosen before export. The exported image looks like the B&W image I posted above but with color.
The in the second I merge the layers before exporting. It appears the entire image is treated as white.
In the third I draw "hello" on a transparent layer with a "soft" brush using different grays then export. Transparent areas are rendered as white, gray or translucent areas opaque or with a strange dithering "effect."
It seems I’m moving outside the realm of StackOverflow, but I’m not sure where this post would be better suited.

ffmpeg command for faster encoding at a decent bitrate with smaller file size
14 septembre 2016, par Blair HolmesI’m currently using an implementation of ffmpeg on my android app. I’m allowing users to take short videos within my app and then when they upload them to the server, I’m crunching them down with ffmpeg to decrease file size so they’re not passing huge amounts of data over the wire.
the problem is, it’s taking forever to encode the videos on the android device. These videos usually aren’t longer than 45 seconds and can take 20 minutes to encode. I’ve done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I’m just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.
Here are the two commands I’ve been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it’s encoding for so long :
ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4I’ve tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don’t want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :
ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4I’d like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it’s difficult to wrap my head around what I should be doing.
EDIT : adding ffmpeg output.
ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4

FFmpeg Android Video cropping speed and perfomance [duplicate]

Fast Video Compression on Android

FFmpeg15 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
}Logcat
