Command of FFMPEG to make a video from Image(JPEG) + Audio(.mp3) & Share video in Whatsapp
22 novembre 2018, par Neel MevadaI am trying to create a video .mp4 file from .mp3 audio & .jpeg image.
I am able to make a video and able to play in Video Players in 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 below Code :
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"));
}
});From this Link I found that i need to use H264 + AAC. but still not able to share video with supported file format
