[ExoLayer] The player has ugly picture when starting play HLS from low bitrate on Amlogic

[Avetri]

ExoPlayer 1.5.1, Android 4.4, Amlogic 812, player demo
Stream's URL http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/sl.m3u8

The player has ugly picture when starting play HLS from a low bitrate. Even if it turns to playing a high bitrate stream.
If I make it to start from a high bitrate stream video looks good as on my LG G2.

I don't get MediaCodec.INFO_OUTPUT_FORMAT_CHANGED code from the MediaCodec::dequeueOutputBuffer().

To start from a high bitrate need to use following changes:

+++ library/src/main/java/com/google/android/exoplayer/hls/HlsChunkSource.java  (revision )

Are you sure the player is switching to the high bitrate stream (without your modification to have it start start with that stream)? If so, it feels like a device specific issue to me?

[Avetri]

Yes, I am sure.
It is very notably on that stream. Bitrate changes and quality of video too.

If it is alright we should see messages like below in logcat:

11-13 02:15:00.676 30906-30906/com.google.android.exoplayer.demo D/EventLogger: videoSizeChanged [640, 360, 0, 1.0]

I get it once, at start of a playing.

Could anybody check it on their Amlogic's devices please?

You should report this issue to AmLogic. I don't think it's a problem with ExoPlayer.
