- Remove an option to use MediaCodec SW decoder from Java layer. - Better handling Java exceptions in JNI - detect exceptions and either try to reset the codec or fallback to SW decoder. - If any error is reported by codec try to fallback to SW codec for VP8 or reset decoder and continue decoding for H.264. - Add more logging for error conditions.
