Subject: [PATCH] media: bcm2835-unicam: Start and stop media_pipeline
|
||
|
|
with same node
|
||
|
|
|
||
|
|
media_pipeline_start and media_pipeline_stop now validate that
|
||
|
|
the pipeline is being started and stopped with the same pipe
|
||
|
|
and pad handles.
|
||
|
|
When running with embedded metadata (eg imx477 and imx708), the
|
||
|
|
start typically happens from the metadata pad, whilst stop is
|
||
|
|
always from the image pad.
|
||
|
|
|
||
|
|
Always pass the image pad to media_pipeline_start to ensure
|
||
|
|
that the calls are balanced.
