Video capturing in portrait mode but the orientation is wrong when played back with a media player
17 octobre 2016, par Ahmed MujtabaI’m trying to make a custom video app. The app captures a video using mediarecorder and uploads it to the website where it’s played on a html5 media player. The issue is that, when I capture the video in portrait mode, the playback video on the website and on vlc player have it’s orientation off by 90 degrees. I have tried various solution on the internet but none work for me.
Here’s what my code for setting up the media recorder :
private bool prepareMediaRecorder() {
Android.Hardware.Camera.Parameters p = mCamera.GetParameters();
List previewSizes = p.SupportedPreviewSizes.ToList();
//mCamera = GetCameraInstance();
//setCameraDisplayOrientation(Activity, cameraId, mCamera);
mediaRecorder = new MediaRecorder();
mCamera.Unlock();
mediaRecorder.SetCamera(mCamera);
mediaRecorder.SetAudioSource(AudioSource.Camcorder);
mediaRecorder.SetVideoSource(VideoSource.Camera);
mediaRecorder.SetOrientationHint(CameraS.result);
if (currentapiVersion >= 16)
{
mediaRecorder.SetProfile(CamcorderProfile.Get(CamcorderQuality.High)); // requires API Level 8 or higher
}
else
{
mediaRecorder.SetProfile(CamcorderProfile.Get(CamcorderQuality.Q480p)); // requires API Level 8 or higher
}
//mediaRecorder.SetVideoFrameRate(30);
mediaRecorder.SetOutputFile(localPath);
mediaRecorder.SetMaxDuration(600000); // Set max duration 60 sec.
mediaRecorder.SetMaxFileSize(50000000); // Set max file size 50M
mediaRecorder.SetVideoSize(previewSizes[0].Width, previewSizes[0].Height);
mediaRecorder.SetPreviewDisplay(mPreview.Holder.Surface);
mediaRecorder.SetOrientationHint(getDisplayOrientationAngle());
try
{
mediaRecorder.Prepare();
}
catch (IllegalStateException e)
{
releaseMediaRecorder();
return false;
}
catch (Java.IO.IOException e)
{
releaseMediaRecorder();
return false;
}
return true;
}
public int getDisplayOrientationAngle() {
//Log.e("", "setDisplayOrientationAngle is call");
int angle;
var mDisplayRotation = Activity.WindowManager.DefaultDisplay.Rotation;
// switch (MeasurementNativeActivity.DisplayRotation) {
switch (mDisplayRotation)
{
case SurfaceOrientation.Rotation0: // This is display orientation
angle = 90; // This is camera orientation
break;
case SurfaceOrientation.Rotation90:
angle = 0;
break;
case SurfaceOrientation.Rotation180:
angle = 270;
break;
case SurfaceOrientation.Rotation270:
angle = 180;
break;
default:
angle = 90;
break;
}
//Log.v("", "media recorder displayRotation: " + mDisplayRotation);
//Log.v("", "media recorder angle: " + angle);
return angle;
}The orientation of the video is fine when played on the phone app but on the website it’s not. I tried to use FFMPEG encoder to rotate the video clockwise. This seemed to fix the orientation of the video, however the aspect ratio of the video is all messed up. The video is stretched vertically and goes off screen.
The command I’m using to rotate and encode the video is as follows :-y -i inputPath -vf scale=640:480,setsar=1,transpose=1 -strict experimental -r 25 -vcodec mpeg4 -b 1000k ab 48000 -ac 2 -ar 22050 destinationPath
I will really appreciate if someone can help me fix either the orientation of the video or the aspect ration after encoding the video.
Cheers !
Edit.

FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE
30 janvier 2020, par Moonsurfer_1I have a question involving multiple audio languages on HLS with FFMPEG.
I’m currently using the following command to mux a transport stream with multiple audio languages into an HLS stream with a master playlist :
ffmpeg -re -i $INPUT_URL -map 0:v -c:v copy -map 0:a -c:a copy -f hls -hls_time 6 -hls_list_size 10 -hls_flags delete_segments+program_date_time -hls_segment_filename "$FULL_OUTPUT_FOLDER/stream_%v_%d.ts" -var_stream_map "v:0,agroup:groupname a:0,agroup:groupname a:1,agroup:groupname a:2,agroup:groupname a:3,agroup:groupname" -master_pl_name master.m3u8 $FULL_OUTPUT_FOLDER/stream-%v.m3u8
The output of this command looks like this :

Could anyone help me with this ?
Thanks !
