After lot of compilling, and testing, i found exactly one commit, that related to this problem. Before that commit, encoded video works perfectly on every device. After this, only with baseline profile, and/or with interlaced fields.<br>

It's an issue with your decoder(s) as they fail if one of the<br>
previously reserved bits is now 1 instead of 0 which they really<br>
should be ignoring, so you should probably send a bug report to the<br>
manufacturer.<br>
<br>
It seems there are a few different devices with the same issue though,<br>
so maybe we should just revert this change since I don't have much<br>
faith in decoder manufactures fixing bugs, especially for older<br>
products.<br>
