We will use MediaEventSource to notify the decoder that this media is not seekable. This eliminate the need for cross-thread reading from members of the readers and make a more consistent thread-model for the readers.

Per discussion, add mMediaSeekable to MediaInfo to indicate if this media is seekable or not when reading metadata.

personally I like this being done in the constructor. not a fan of C++11 inline member initialisation

I would have merged part 1 and part2 as part 1 includes piece of code that is removed from part2 and you get to wonder where the logic come from. would be more apparent in a combined patch

It comes in handy when every constructor initializes the member with the same value or when there is no constructor at all which is the case of MediaInfo.

Which portion of part2 do you mean that can be moved to part1? part2 is all about removing code.

You can use delegated constructor now https://developer.mozilla.org/en-US/docs/Using_CXX_in_Mozilla_code
so you don't have to initialize the value in each constructor. only one
