Subject: [PATCH] media/v4l2_m2m: In buffered mode run jobs if either
|
|
port is streaming
|
|
|
|
In order to get the intended behaviour of the stateful video
|
|
decoder API where only the OUTPUT queue needs to be enabled and fed
|
|
buffers in order to get the SOURCE_CHANGED event that configures the
|
|
CAPTURE queue, we want the device to run should either queue be
|
|
streaming.
