This is a quick fix for regression introduced by the upstream
commit e8908f5aee in h264 videoparser.
The patch is disabling the passthrough mode, otherwise it will
break multi-layer mvc stream parsing.

Subject: [PATCH] videoparsers: h264: Disable passthorugh mode enabling
|
|
|
|
Enabling passthorugh mode for optimization is cauing multiple
|
|
issues while parsing MVC streams. Specifically if streams have
|
|
two separate layers (base-view and non-base-view).
|
|
|
|
Proper fixes needed in many places:
|
|
(handle prefix nal unit, handle non-base-view slice nal extension,
|
|
fix the picture_start detection for multi-layer-mvc streams etc)
