2021-03-12libcamera: gst: Fix double-free when acquire_buffer failsMarian Cichy
If gst_buffer_pool_acquire_buffer in gst_libcamera_task_run fails, the unique_ptr to the request-object gets reset and hence, its destructor is called. However, the wrap-object points to the same object and is still alive at this moment. When the task_run-function is finished, the destructor of the wrap-object is called, which in return calls the destructor of the request-object again. Instead of taking care of both, the request and the wrap-object, we can move the request to the wrap which will then effectively take care of the request object automatically.

2021-03-12test: delayed_controls: Fixup tests after recent DelayedControls changesNaushir Patuck
The recent fixes applied to DelayedControls change the behavior of the library. As such, the tests ended up failing as they relied on the old behavior of the helper. Update the tests to account for the new behavior and get the tests passing again. Specifically, the following changes have been made for each test: singleControlNoDelay(): - Add a call to reset() to initialise internal DelayedControls state only after setting the control on the device. - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from 1 onwards, as we will never have a queue item at frame 0, since the reset() handles that. singleControlWithDelay(): - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from 1 onwards, as we will never have a queue item at frame 0, since the reset() handles that. dualControlsWithDelay() and dualControlsMultiQueue(): - Trigger a first frame start by calling applyControls() as a pipeline handler would. - Test frames from (startOffset + 1) onwards, as we will never have a queue item at frame startOffset. - Use the max delay (2 in this case) to determine the expected result value.

There was an off-by-one error in DelayedControls::get() when picking controls from the queue to return back to the pipeline handler. This is only noticeable as small oscillations in brightness when closely viewing frame while AGC is running.

2021-03-12libcamera: delayed_controls: Remove spurious no-op queued controlsNaushir Patuck
In DelayedControls::applyControls(), the controls queue would be extended via a no-op control push to fill the intermittent slots with unchanged control values. This is needed so that we read back unchanged control values correctly on every frame. However, there was one additional no-op performed on every frame that is not required, meaning that any controls queued by the pipeline handler would have their write delayed by one further frame. The original StaggeredCtrl did not do this, as it only had one index to manage, whereas DelayedControls uses two. Remove this last no-op push so that the pipeline_handler provided controls would be written on the very next frame if possible. As a consequence, we must mark the control update as completed within the DelayedControls::applyControls() loop, otherwise it might get reused when cycling through the ring buffer.

2021-03-12libcamera: delayed_controls: Remove unneeded write when starting upNaushir Patuck
On DelayedControls::reset(), the values retrieved from the sensor device were added to the queues with the updated flag set to true. This would cause the helper to write out the value to the device again on the first DelayedControls::applyControls() call. This is unnecessary, as the controls written are identical to what is stored in the device driver. Fix this by explicitly setting the update flag to false in DelayedControls::reset() when adding the controls to the queue. Additionally, use the Info() constructor when adding items to the queue for consistency.

2021-03-12libcamera: delayed_controls: Add notion of priority writeNaushir Patuck
If an exposure time change adjusts the vblanking limits, and we set both VBLANK and EXPOSURE controls through the VIDIOC_S_EXT_CTRLS ioctl, the latter may fail if the value is outside of the limits calculated by the old VBLANK value. This is a limitation in V4L2 and cannot be fixed by setting VBLANK before EXPOSURE in a single VIDIOC_S_EXT_CTRLS ioctl. The workaround here is to have the DelayedControls object mark the VBLANK control as "priority write", which then write VBLANK separately from (and ahead of) any other controls. This way, the sensor driver will update the EXPOSURE control with new limits before the new values is presented, and will thus be seen as valid. To support this, a new struct DelayedControls::ControlParams is used in the constructor to provide the control delay value as well as the priority write flag.

As the CameraSensor::resolution() method is widely used in the library code base to retrieve the maximum frame size the sensor can produce, in case it is smaller than the pixel area size the returned size cannot be used to configure the sensor correctly.

2021-03-04libcamera: pipeline: simple: Support camera sensors that contain an ISPLaurent Pinchart
Camera sensors can include an ISP. For instance, the AP1302 external ISP can be connected to up to two raw camera sensors, and the combination of the sensors and ISP is considered as a (smart) camera sensor from libcamera's point of view. The CameraSensor class has limited support for this already. Extend the simple pipeline handler to support such sensors, by using the media entity corresponding to the ISP instead of the raw camera sensor's entity. We don't need to handle the case where an entity in the SoC would expose the MEDIA_ENT_F_PROC_VIDEO_ISP function, as pipeline containing an ISP would have a dedicated pipeline handler. The implementation is limited as it won't support other multi-entity camera sensors (such as CCS). While this would be worth supporting, we don't have a test platform with a CCS-compatible sensor at this point, so let's not over-engineer the solution. Extending support to CCS (and possibly other sensor topologies) will likely involve helpers that can be used by other pipeline handlers (such as generic graph walk helpers for instance) and extensions to the CameraSensor class.

2021-03-04libcamera: pipeline: simple: Walk the pipeline by following the first linkDafna Hirschfeld
When walking the pipeline, follow the first link of each source pad. This patch removes a redundant condition for choosing the link: "(link->flags() & MEDIA_LNK_FL_ENABLED) || !(link->flags() & MEDIA_LNK_FL_IMMUTABLE)" since it always returns true.

2021-03-04libcamera: v4l2_videodevice: Print fd value in log prefixLaurent Pinchart
When opening a V4L2VideoDevice multiple times, for instance to run multiple jobs on a M2M device, it's useful to attribute log messages to a particular instance. Include the device fd in the log prefix. This turns the existing output [1:43:01.958321522] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[cap]: Queueing buffer 0 [1:43:01.958350060] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[cap]: Queueing buffer 1 [1:43:01.958365137] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[cap]: Queueing buffer 2 into [1:43:01.958321522] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[14:cap]: Queueing buffer 0 [1:43:01.958350060] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[14:cap]: Queueing buffer 1 [1:43:01.958365137] [277] DEBUG V4L2 v4l2_videodevice.cpp:1440 /dev/video0[14:cap]: Queueing buffer 2 Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
2021-03-04libcamera: v4l2_device: Make fd() function constLaurent Pinchart
There are use cases for getting the file descriptor of a const V4L2Device instance, for instance to print it in a log. Make the function const. There's little risk of abuse here (as in code then performing operations on the file descriptors that conceptually modify the V4L2 device), as the fd() function is protected.
