Is there any update on this issue?

neurospeech commented 7 years ago

Not yet, I don't have physical device yet with Android N, as our devices did not yet receive any updates. But we will let you know soon if we find anything. If it is possible, could you setup HockeyApp and find some more information about crash?

Shuayd commented 7 years ago

Not sure if this helps but you can use this site free for use and have access to the new android physical devices. https://testobject.com/

Thanks

neurospeech commented 7 years ago

ffmpeg will never run on Android 6.0 and after, as Google has disabled text relocations and ffmpeg team has lots of text relocations written in assembly modules, which they have not shown any interest in fixing it.

For Android 6.0 and after, you can use Xamarin.Android.MP4Transcoder , please read more about it here,
