2024-05-08libcamera: Drop 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 block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>
2022-07-04gstreamer: Pass Stream to RequestWrap::addBuffer()Laurent Pinchart
For symmetry with RequestWrap::removeBuffer(), pass the Stream pointer to addBuffer(). This handles streams at the GstPad level instead of the GstBuffer level, which allows making the GstLibcameraPool API a bit cleaner by removing the gst_libcamera_buffer_get_stream() helper function.

We borrowed a GstBuffer from the pool, if preparing the buffer failed, we need to push it back to avoid leaking it.

Macros used in gstreamer (e.g. G_DEFINE_TYPE) are functions. The end semicolons with the macros are unnecessary.

2020-08-25meson: Remove -Wno-unused-parameterLaurent Pinchart
We build libcamera with -Wno-unused-parameter and this doesn't cause much issue internally. However, it prevents catching unused parameters in inline functions defined in public headers. This can lead to compilation warnings for applications compiled without -Wno-unused-parameter. To catch those issues, remove -Wno-unused-parameter and fix all the related warnings with [[maybe_unused]].

2020-03-07gst: libcamerasrc: Prevent src task deadlock on exhausted buffer poolJakub Adam
Allow GstLibcameraPool to notify the source when a new buffer has become available in a previously exhausted buffer pool. This can be used to resume a src task that got paused because it couldn't acquire a buffer. Without this change the src task will never resume from pause once the pool gets exhausted. To trigger the deadlock (it doesn't happen every time), run: gst-launch-1.0 libcamerasrc ! queue ! glimagesink Signed-off-by: Jakub Adam <jakub.adam@collabora.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
