Issue Playing HD Video

Archived
1

I have a VideoPlayer node which I’m trying to play a video in. I’m able to get the 360p version to play, but not the 720p or 1080p version. The other versions just sit at the loading screen. Has anyone seen similar issues or might have an idea? I’m playing this on a Roku Stick, on 1080p display.

This happens with other videos of the same resolution as well.

Using MediaInfo(https://mediaarea.net/en/MediaInfo)

You can see some differences in the 360p and the 720p versions in the encoding information.

I have to imagine that the Roku is processing the 720p encoding information properly, as the 720p video is perfectly valid.

Does it have to do with CABAC? (Which the 720p+ versions use)

360p info:

Format profile                           : Baseline@L3
Format settings, CABAC                   : No
Format settings, ReFrames                : 1 frame
Format settings, GOP                     : M=1, N=60

vs. 720p info:

Format profile                           : Main@L3.1
Format settings, CABAC                   : Yes
Format settings, ReFrames                : 3 frames

The 720p video doesn’t define a maximum bit rate either for the video and audio streams.

The 720p video also includes additional ‘Title’ and ‘Encoded date’ fields that the 360p version doesn’t include.

Could the header differences be parsed improperly within the Roku? Or can their media player not handle the encoding type for the video stream?

I’m guessing their media player code can’t handle the encoding. I’m tired of waiting on Roku to fix handling “odd” encoding schemes, and I don’t expect this to be fixed in any reasonable amount of time, especially considering they hardly ever respond to questions in the forum.

Thanks for the details! I’ll check out that program you suggested and see if i can come up with some work around.
