Converting .3gp file into mp4 file in android using ffmpeg
8 août 2013, par user2171513I want to convert .3gp file into .mp4 file with resolution modified in Android using ffmpeg.
I want to increase the resolution of the video from its standard resolution to 1920x1080.So far I have been successful in
1) extracting .h264 video file from .3gp file and increase its resolution
2) extracting .aac audio file from .3gp file.Now I want to combine them back into .mp4 file. The commands that I have used to extract this .h264 and .aac files are :
./ffmpeg -i 1.3gp -vbsf h264_mp4toannexb -s 1920x1080 1.h264
./ffmpeg -i 1.3gp -ab 160k -ac 2 -ar 48000 -vn -strict -2 1.aacThe command that I have tried to merge them back is
./ffmpeg -i 1.h264 -i 1.aac -map 0:0 -map 1:0 -strict -2 1.mp4The 1.mp4 that gets generated at the end basically has audio only at few sync frames of video. (Thats what I feel , because the audio is present at specific intervals within the video)
Can anyone please help in figuring out what am I missing here.
EDIT :
So basically I want to concat 4 different videos of 4 different resolution and type.1)
./ffmpeg -i 1.mp4
Video: h264 (High), yuv420p, 1920x1080, 16959 kb/s, 29.85 fps, 90k tbr, 90k tbn, 180k tbc
Audio: aac, 48000 Hz, stereo, s16, 106 kb/s2)
ffmpeg -i 2.mp4
Video: h264 (Constrained Baseline), yuv420p, 640x480, 3102 kb/s, 29.99 fps, 90k tbr, 90k tbn, 180k tbc
Audio: aac, 48000 Hz, stereo, s16, 93 kb/s3)
ffmpeg -i 3.3gp
Video: h263, yuv420p, 1408x1152 [PAR 12:11 DAR 4:3], 2920 kb/s, 15 fps, 15 tbr, 15360 tbn, 29.97 tbc
Audio: amrnb, 8000 Hz, 1 channels, flt, 12 kb/s4)
ffmpeg -i 4.3gp
Video: h264 (High), yuv420p, 352x288 [PAR 12:11 DAR 4:3], 216 kb/s, 24 fps, 24 tbr, 24 tbn, 48 tbc
Audio: aac, 44100 Hz, stereo, s16, 92 kb/sSo I am converting them to mpegts using following commands
./ffmpeg -i 1.mp4 -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 1.ts
./ffmpeg -i 2.mp4 -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 2.ts
./ffmpeg -i 3.3gp -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 3.ts
./ffmpeg -i 4.3gp -c:v libx264 -vf scale=1920:1080 -r 60 -c:a aac -ar 48000 -b:a 160k -strict experimental -f mpegts 4.tsthen concatenating the .ts files into f.ts and then creating a final .mp4 file from it using
cat 1.ts 2.ts 3.ts 4.ts > f.ts
./ffmpeg -i f.ts -c copy -bsf:a aac_adtstoasc output.mp4But my f.ts also doesnt seem to play correctly in VLC on linux, it plays first 2 mp4's video + audio and it plays last .3gp's audio only.(Same for output.mp4 too) Could you please help me in figuring out what am I missing ?
Thanks

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 ?

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);

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 {
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

Log.d("progress", message);
pd.show();
}
@Override

Log.d("failure", message);

}
@Override
public void onStart() {
Log.d("Start", "merge started");
