Command of FFMPEG to make a video from Image(JPEG) + Audio(.mp3) & Share video in Whatsapp

Question

I am trying to create a video .mp4 file from .mp3 audio & .jpeg image.

I am able to create a video and able to play it in video players on Android devices.

But after creation of file when I tried to share that video in WhatsApp, at that time it shows a message "The file format not supported".

I am using below FFMPEG command:

"-loop 1 -r 1 -i " + imageFilePath + " -i " + audioFilePath + " -c:v libx264 -crf 27 -tune stillimage -c:a copy -pix_fmt yuv420p -preset ultrafast -shortest " + pathOutputVideo(sectionName);

And for sharing video, I am using code listed below:

  MediaScannerConnection.scanFile(ShareQuestionAudioActivity.this, new String[]{FfmpegController.pathOutputVideo(qModel.getSectionName().toUpperCase().replaceAll(" ", "_"))},
                null, new MediaScannerConnection.OnScanCompletedListener() {
                    public void onScanCompleted(String path, Uri uri) {
                        Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
                        shareIntent.setType("video/*");
                        shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(FfmpegController.pathOutputVideo(qModel.getSectionName().toUpperCase().replaceAll(" ", "_"))));
                        startActivity(Intent.createChooser(shareIntent, "Share Question"));
                    }
                });

I foundhere that I need to use H.264 + AAC. But I'm still not able to share video with supported file format .

Answer 1

As already discussed in the comments the problem occurs due to the audio not to be encoded using AAC codec since -c:a copy was used on mp3 audio files.

The solution to this is to tell ffmpeg to re-encode audio stream to AAC using -c:a aac . More examples on how to encode AAC can also be found here .
