Black/Empty frames at beginning of video file when file Cut using FFmpeg [closed]
28 octobre 2024, par d0tb0tI am cutting a video using ffmpeg and facing the Black/Empty frame at the start issue.

Android Studio - Append two videos but showing black screen
6 septembre 2020, par DarkhmarFirst of all hello,


When I add another mp4 file at the end of an mp4 file, the video looks completely black screen but I can get the video sounds.


If I add a copy of a video to the end of it, I saw that there was no problem, but this is not a scenario I want.


I am getting the "text relocations" error when merging with the FFmpeg library. (This problem is fixed when I change this library version, but I have other problems. Therefore, mp4parser is an alternative I see.)


The piece of code that allows the videos to be merged is as follows. Thank you from now.


private void appendTwoVideos(String firstVideoPath, String secondVideoPath) {
 try {
 Movie[] inMovies = new Movie[2];

 inMovies[0] = MovieCreator.build(firstVideoPath);
 inMovies[1] = MovieCreator.build(secondVideoPath);

 List<track> videoTracks = new LinkedList<>();
 List<track> audioTracks = new LinkedList<>();

 for (Movie m : inMovies) {
 for (Track t : m.getTracks()) {
 if (t.getHandler().equals("soun")) {
 audioTracks.add(t);
 }
 if (t.getHandler().equals("vide")) {
 videoTracks.add(t);
 }
 }
 }

 Movie result = new Movie();

 if (audioTracks.size() > 0) {
 result.addTrack(new AppendTrack(audioTracks
 .toArray(new Track[audioTracks.size()])));
 }
 if (videoTracks.size() > 0) {
 result.addTrack(new AppendTrack(videoTracks
 .toArray(new Track[videoTracks.size()])));
 }

 BasicContainer out = (BasicContainer) new DefaultMp4Builder().build(result);

 @SuppressWarnings("resource")
 FileChannel fc = new RandomAccessFile(DIRECTORY_PATH + "output.mp4", "rw").getChannel();
 out.writeContainer(fc);
 fc.close();
 } catch (FileNotFoundException e) {
 e.printStackTrace();
 } catch (IOException e) {
 e.printStackTrace();
 }
}

Getting small file size from ffmpeg [duplicate]
20 février 2020, par sukachI am not an ffmpeg expert. I am trying to get some movies converted to a smaller DIVX file for a cheap portable DVD player for a family trip. The movies are for my kids so I’m not too concerned about quality.
The DVD player is a 10.1", 1024x600 screen. It says it supports DIVX/MPEG2 files. It took me a lot of experimentation to get the right ffmpeg settings to even get it to work, but I found another answer that provided a very complex set of parameters that ultimately worked.
I have converted about 20 movies with this setting and every one results in a file size of 1.1GB. I have tried different file sizes and crf settings and it is the same every time.
Here is an example. First, the original file :
