Subject: [PATCH] vc04_services: bcm2835-codec: Correct alignment requirements
|
|
for YUYV
|
|
|
|
The firmware wants the YUYV format stride alignment to be to a multiple
|
|
of 32pixels / 64 bytes. The kernel driver was configuring it to a multiple
|
|
of 16 pixels / 32 bytes, which then failed when it tried starting to
|
|
stream.
|
|
|
|
Correct the alignment requirements.
