How to set outputFileformat?

[prashantgunit]

I have an issue regarding out file format. Recorded file format change to 3gp in my micromax phone. Otherwise it is working fine in my other phones. Please help me out.

[pedroSG94]

If you try reproduce any mp4 file in your device, it works fine? Can you share me device model and api version?

[prashantgunit]

Device Model is Micromax E484 android version is 5.1 by default camera is recording in .3gp format and file is shown in sdcard like this in image

Write a log in this conditional to make sure your encoder create key frame and start record video: https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/rtplibrary/src/main/java/com/pedro/rtplibrary/base/Camera1Base.java#L619

It is not working when i changed file format to mediaMuxer = new MediaMuxer(path, MediaMuxer.OutputFormat.MUXER_OUTPUT_3GPP); Is there any workaround to resolve the issue?

[pedroSG94]

Did you try write a log to know if your device start mediamuxer? https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/rtplibrary/src/main/java/com/pedro/rtplibrary/base/Camera1Base.java#L619

Hi, I have write the log and mediaMuxer is not getting started. What should i do now?

[pedroSG94]

It means that your encoder never mark a keyframe so mediamuxer never start. Try record 2mins video and see if sometime your encoder mark some keyframe. I will try find a way to force mark that frame but I don't know if I can do it. What mode and view are you using? (rtmpcamera1 with surfaceview for example, rtmcamera1 with lightopengl, etc)

[prashantgunit]

i am using rtmpcamera1 with surfaceview. 2 mins recording does not capture any frame.

[prashantgunit]

when i remove this condition

 if (info.flags == MediaCodec.BUFFER_FLAG_KEY_FRAME
          && !canRecord
          && videoFormat != null
          && audioFormat != null) {
}

Got this error in logcat

 java.lang.IllegalStateException: Muxer is not initialized.

[pedroSG94]

Go to: https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/encoder/src/main/java/com/pedro/encoder/video/VideoEncoder.java#L415 Replace:

if (buffers != null) {
              getH264Data.onSPSandPPS(buffers.first, buffers.second);
              spsPpsSetted = true;
}

To:

if (buffers != null) {
              getH264Data.onVideoFormat(videoEncoder.getOutputFormat());
              videoInfo.flags = MediaCodec.BUFFER_FLAG_KEY_FRAME;
              getH264Data.onSPSandPPS(buffers.first, buffers.second);
              spsPpsSetted = true;
            }

[prashantgunit]

Not working. Same result with 0 bytes file

[pedroSG94]

Last 2 shoot. I haven't more ideas for now. If no work I only can think that your device can't record mp4 because your native camera can't do it. Try force hardware and software video encoders.

//hardware
rtmpCamera1.setForce(CodecUtil.Force.HARDWARE, CodecUtil.Force.FIRST_COMPATIBLE_FOUND);
//software
rtmpCamera1.setForce(CodecUtil.Force.SOFTWARE, CodecUtil.Force.FIRST_COMPATIBLE_FOUND);

If no work try use lightopenglview instead of surfaceview. Also combine it with both previous suggestions.

[prashantgunit]

Now i am gettting this in my logcat

E/VideoEncoder: Valid encoder not found
07-21 17:46:09.378 27017-27017E/VideoEncoder: Valid encoder not found
07-21 17:46:09.384 27017-27017 E/VideoEncoder: VideoEncoder need be prepared, VideoEncoder not enabled

[pedroSG94]

When you force hardware, software or using lightopenglview?

[prashantgunit]

when i use software and surfaceview

[pedroSG94]

Try hardware and lightopenglview. If no work I don't know more ways to solve it.
