Converting Real Media with ffmpeg

7 août 2013, par Eric Arenson

I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I'm able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

[avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

It may have something to do with the funky format of these Real Media files :

Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?

Including the ffmpeg command (thank you to @Mondain for teaching me about the stream mapping !) and output :

FFMPEG HLS Multiple audio languages with var_stream_map - EXT-X-MEDIA:TYPE doesn't contain LANGUAGE

30 janvier 2020, par Moonsurfer_1

I 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 :

While this does seem to work with VLC, I need the EXT-X-MEDIA:TYPE tag to contain the LANGUAGE property. (the player I’m working with uses it to parse the audio tracks’ language) I can’t figure out how to do that based on the documentation I’ve found.

Could anyone help me with this ?

Thanks !

Video capturing in portrait mode but the orientation is wrong when played back with a media player

17 octobre 2016, par Ahmed Mujtaba

I’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.
