Tools/Techniques for investigating video corruption — ffmpeg / libavcodec
17 juillet 2013, par GopherkhanIn my current work I'm trying to encode some images to h264 video using the FFMPEG's C library. The resulting video plays fine in VLC, but has no preview image. The video can play in VLC and Mplayer on ubuntu, but won't play on Mac or PC (in fact, it causes a "VTDecoderXPCService quit unexpectedly" error on Mac).
If I run the resulting file through FFMPEG using the command line, the resulting file has a preview image, and plays correctly everywhere.
Apparently the file that I get out of the program is corrupt in some weird place, but I don't have any output during my compilation or run to indicate where. I can't share my code at the moment (work code isn't open source yet :-( ), but I have tried a number of things :
- Writing only header and trailer data (av_write_trailer) and no frames
- writing frames only minus the trailer (using avcodec_encode_video2 and av_write_frame)
- Adjusting our time_base and frame pts values to encode only one frame per second
- Removing all variable frame rate code
- Numerous other variants that I won't bother you with here
In creating my project, I've also followed the following tutorials :
And consulted the deprecated ffmpeg functions list
And compiled FFMPEG on ubuntu according to the official doc
And consulted numerous StackOverflow questions :
- Raw H264 frames in mpegts container using libavcodec
- How to encode Bitmaps into a video using MediaCodec ?
- How to convert RGB from YUV420p for ffmpeg encoder ?
- Encoding H.264 video using FFmpeg C API
- ffmpeg : how to save h264 raw data as mp4 file
But every run of the program runs into the exact same problem.
My question is, is there anything obvious that causes a programmatic run of FFMpeg to differ from a console run (e.g., an incomplete finalization, some threading issues, etc.) ? Like some obvious reason that a console run could repair a corrupted file ? Or is there a decent tool/method for inspecting a video file and finding the point of corruption ?

Create a video with audio only on one channel
6 février 2018, par Jude OsbornI’m trying to create 5 videos that each play audio only in one channel. So, for example, one video only plays audio in the right front, another only in the back left, another only in the center, etc.
The videos are currently stereo. Can I use ffmpeg to accomplish this ?

Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"
5 juin 2017, par Akash DubeyI am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4 :
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};Below is My code :
private void changeAudioofVideo(String selectedUri, String videoPath) {
String[] complexCommand;
File f = new File("/storage/emulated/0");
if (!f.getParentFile().exists())
f.getParentFile().mkdirs();
if (!f.exists())
try {
f.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
file1 = new File(videoPath);
if (file1.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
file2 = new File(selectedUri);
if (file2.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
String rootPath = f.getPath();
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};
FFmpeg ffmpeg = FFmpeg.getInstance(this);
try {
//Load the binary
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {
}
@Override
public void onFailure() {
}
@Override
public void onSuccess() {
}
@Override
public void onFinish() {
}
});
} catch (FFmpegNotSupportedException e) {
// Handle if FFmpeg is not supported by device
Toast.makeText(getApplicationContext(), "Not Supported by Device", Toast.LENGTH_LONG).show();
}
try {
final String finalRootPath = rootPath;
ffmpeg.execute(complexCommand, new FFmpegExecuteResponseHandler() {
@Override
public void onSuccess(String message) {
Log.d("Success", message);
Toast.makeText(getApplicationContext(), "Successful" + finalRootPath.toString(), Toast.LENGTH_LONG).show();
Uri path = Uri.parse(finalRootPath + "/output.mp4");
playVideo(path.toString());
}
@Override
public void onProgress(String message) {
Log.d("progress", message);
pd.show();
}
@Override
public void onFailure(String message) {
Log.d("failure", message);
pd.dismiss();
}
@Override
public void onStart() {
Log.d("Start", "merge started");
}
@Override
public void onFinish() {
Log.d("finish", "merge finish");
pd.dismiss();
}
});
} catch (FFmpegCommandAlreadyRunningException e) {
e.printStackTrace();
}
