Hello,
After the Roku box firmware updated to Firmware 2.9 build 1553 I am no longer able to play on Roku videos that were previously playing. Can anyone tell me please what properties should have a video in order to play on Roku? What exactly has changed with the new update that prevent previously playing video to play anymore on the Roku box?
Example of video that used to play on Roku before and doesn't play anymore:

Curiously a video ability of playing on Roku can be influenced only by changing the audio bit rate:

I have also tried to change the numbers of Reference Frames (even with 1 reframe doesn't play) and the keyframe interval from 300 to 200 but the videos still don't play on the Roku box.
Please advise me what encoding settings should I use to allow all video to play on Roku (at this moment from 14 videos re-encoded using their default bit rates and frame rates only 4 played on Roku - frame rate doesn't seem to be an issue because I have videos at 24 FPS that play on Roku and others at the same frame rate that don't for example).
Thank you,
Florin
