The patch I proposed does not fix this issue on the FireTV stick. And, as I noted on the mailing list, the technique used in my patch is invalid according to the MediaCodec? documentation. So at this time there is no known fix for this issue.

Thanks for the clarification!

If there is anything I can do to contribute to narrow down this issue (e.g. logs, etc.) just let me know!
