ExoPlayer to use customized MediaCodecSelector

Question

On my targeting device I need to force ExoPlayer to use a specific codec, during testing if I modify the getDecoderInfo() function of MediaCodecSelector DEFAULT implementation, things work well.

However for the real product I prefer not to modify the source of ExoPlayer. I saw some post saying you can implement your own MediaCodecSelector, but I failed to figure out how.

If I'm to subclass SimpleExoPlayer, since the use of MediaCodecSelector.DEFAULT is hardcoded into buildVideoRenderers() of SimpleExoPlayer, I'm thinking to override buildVideoRenderers(), however I don't have access to the private properties, and even if I had it will end up with duplicated code.

Or if I'm to implement ExoPlayer, seems it will depend on even more private classes.

I suppose the standard way to do it is none of the above.

Answer 1

I ended up using the following factory function of ExoPlayerFactory: public static ExoPlayer newInstance(Renderer[] renderers, TrackSelector trackSelector). Where I create the Renderer with my own MediaCodecSelector.

Then only difference is how to set up surface view, and sendMessage of type MSG_SET_SURFACE works for me.
