Then we have to do find() and if (it != end()), and that's what I want to avoid :D Don't you remember how much copy&pasting there was of exactly that? > > Anyway, these comments are not on this patch > > > + ANDROID_SYNC_MAX_LATENCY_UNKNOWN); > > > > /* Flash static metadata. */ > > char flashAvailable = ANDROID_FLASH_INFO_AVAILABLE_FALSE; > > diff --git a/src/libcamera/control_ids.yaml b/src/libcamera/control_ids.yaml > > index d92f29f5..9d4638ae 100644 > > --- a/src/libcamera/control_ids.yaml > > +++ b/src/libcamera/control_ids.yaml > > @@ -622,6 +622,16 @@ controls: > > detection, additional format conversions etc) count as an additional > > pipeline stage. > > > > + - MaxLatency: > > + type: int32_t > > + draft: true > > + description: | > > + The maximum number of frames that can occur after a request (different > > + than the previous) has been submitted, and before the result's state > > + becomes synchronized.
