2024-11-04gstreamer: Implement caps negotiation for video/x-bayerJohannes Kirchmair
The parsing of video/x-bayer sources from string makes it possible to use cameras providing e.g SGRBG8 streams via gst-launch. Like: gst-launch-1.0 libcamerasrc camera-name=<cam> ! video/x-bayer,format=grbg Without this change the gstreamer plugin complains about "Unsupported media type: video/x-bayer".

2024-07-26gstreamer: Fix width and height range handlingHou Qi
This changes is fixing critical error message "gst_value_set_int_range_step: assertion 'start < end' failed" observed when building GStreamer caps from a stream configuration whose size range holds a single size. GStreamer range step definition requires distinct min and max values definitions, otherwise above error message is output. libcamera SizeRange instance may return a single size leading to identical min and max values. Add a conditional check where the min and max of the range are distinct during iterating the supported sizes for each pixelformat. To prevent appending structures that are already expressed with this update, gst_caps_merge_structure() is used in place of gst_caps_append_structure().

2024-05-09libcamera: Drop remaining file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment blocks in all remaining locations that were not caught by the automated script as they are out of sync with the file name.

2022-11-21gstreamer: Do not lookup controls by idJacopo Mondi
The libcamerasrc element looks for the availability of the FrameDurationLimits control by looking it up by numeric control id. The ControlinfoMap::find(unsigned int i) function searches the control numerical identifier on the ContorlInfoMap::idMap_ class member, which might be not initialized if the pipeline handler does not register any control, causing an invalid memory access. Avoid looking up the control by numerical id and use the ControlId instance instead to prevent that.

2022-11-12gstreamer: Provide framerate support for libcamerasrcRishikesh Donadkar
Control the framerate by passing the controls::FrameDurationLimits during Camera::start(). Framerate in gstreamer is expressed as GST_TYPE_FRACTION so we maximise on maintaining it as a fraction throughout and only do arithematic computations as and when required (to compute frame-duration and vice-versa). To weed out abritrary framerate as input, place the clamping via the controls::FrameDurationLimits provided after camera::configure() phase. This is handled by a helper function gst_libcamera_clamp_and_set_frameduration(). Set the bound checked framerate (done in the above mentioned helper) into the caps and pass the ControlList containing the frame-duration to Camera::start(ctrls).

2021-08-26gstreamer: Fix usage of default size for fixationNicolas Dufresne
Pipeline managers sets a default value to StreamConfiguration::size. The original fixation code was attempting to use it, but as it was truncating the caps to its first structure it would never actually find a best match. In this patch, instead of truncating, we weight various matches using the product of the width and height delta. We also split delta from ranges apart and prefer fixed size over them as ranges are not reliable. This patch also removes the related todo, as it seems that libcamera core won't go further then providing this default value and won't be sorting the format and size lists.
