Bug with Shield + Roku involving aspect ratio only when hardware acceleration is used
This bug has been reported to the Roku developer as it only manifests on my Rokus and not on my other devices but I thought that it might be helpful to directly address this on the Shield's forum:
I have been testing my Shield TV's server and I ran into a problem that only shows up on the Rokus, both the Ultra and the Roku 3. My Shield (as a player), My Fire TV and my Raspberry PI do not have the problem.
At first I thought it was the shrunken picture problem that we found on the Ultra earlier as the picture is shrunken in the same way horizontally but, when I switched over to my 3 the problem was also there.
After investigating I found that my regular server (on a Windows 10 computer that cannot use HW acceleration) did not produce the problem and then I looked for differences.
I found that the Shield was using hardware acceleration and my regular server was not.
I turned off that on the Shield and the problem went away I turned it back on and the problem reappeared.
Again this only shows on my Rokus and it shows on all of them. (I have 4 a Roku Ultra, two Roku 3s and a Roku 1)
The problem seems to happen on many, but not all, transcoded videos.
The attached zip file has all my logs plus the XML for a problem file and the Ultra's logs.
To produce the Ultras logs I first turned on HW acceleration on my Shield the I started the Plex app.
Then I played a short part of the problem file and verified the problem Then I stopped Playback.
Then I turned OFF HW accel and started playback again and verified proper playback.
I Then stopped the playback and captured the Ultra's logs.
If this is a problem in the server then it only manifests on my Rokus and if it is a problem with the Rokus then they are somehow treating streams produced by HW accel differently than streams produced regularly.
I hope this can get resolved either on my Rokus or in the Shield's server as I seem to have much better performance if HW acceleration is used on the Shield.
Thanks for looking into the problem.
