@wcoder Thank you for your feedback! Can you include more information about how you are using AVFileType and what behavior you are expecting?

If you could upload a small sample project that demonstrates the issue that would be the best way for us to investigate further.

[yauhenipakala]

Converting video from mov to mp4:

var exportSession = AVAssetExportSession.FromAsset(asset, AVAssetExportSession.PresetPassthrough);
exportSession.OutputFileType = AVFileType.Mpeg4;
//...

[spouliot]

Try

exportSession.OutputFileType = AVFileTypes.Mpeg4.GetConstant ();

exportSession.OutputFileType = AVFileType.Mpeg4;

should work, but you'll get an obsolete warning from the compiler.

Thanks for your reply!

Yes, I use this string.

But I think it needs to describe this choice (.Mpeg4 means .mp4) somewhere to avoid unnecessary confusion.

@wcoder Glad to hear that you were able to resolve the issue!

I can see how the MS documentation might be confusing - it looks like the Apple docs mention that .Mpeg4 means .mp4 but MS does not.

I've marked this as a documentation enhancement. However, this does not necessarily mean we will take actions on it as we still need to discuss its feasibility internally and make sure it is not conflicting with other features.
