v4l2loopback (0.13.0) unstable; urgency=medium
[ IOhannes m zmölnig ]
* Set device_caps in init_vdev() for all kernel-versions (not just >4.7.0)
* Don't set the V4L2_CAP_DEVICE_CAPS on device_caps
* only set (struct video_device).device_caps on linux>=4.7.0
* pre-processor directives should be left-aligned
* tabify
* Drop obsolete ISSUE_TEMPLATE
* Mention that people should do research before creating a new ticket
* document that we expect people to do some research before creating a ticket
* document that people must have a proper bulid-environment
[ mpromonet ]
* reset ready_for_capture flag processing VIDIOC_STREAMOFF
[ IOhannes m zmölnig ]
* redirect people for StackOverflow for general help.
* rule to get the latest&greatest .clang-format for the linux-kernel
* clang-format -i *.c *.h
* fixed whitespace in comments and strings
* use $() rather than ``
* use more frames for setting caps.
* document that GStreamer-1.0 is required (rather than GStreamer-0.10)
* rename _SIZE_MAX_WIDTH to _SIZE_DEFAULT_MAX_WIDTH (same for HEIGHT)
* Add clang-format target
* comment formatting
* switched v4l2_loopback_init() for a more complete v4l2_loopback_add()
* per-device max_width/max_height
* store card-label per device
* copy newly created video-device back
* indentation
* use per-device name rather than the global ones
* switching free_devices() to idr-iterator
* getting rid of static number of devices...
* limit card_label to 32 chars (like v4l2_capability->card)
* make sure to neither exceed size of cap->card nor dev->card_label
* prevent out-of-bounds access to exclusive_caps[]
* less ambiguous wording when MAX_DEVICES is exceeded
* allow device_nr > MAX_DEVICES
* less verbose output
* use video_nr for initial devices
* macro for the default value of EXLCUSIVE_CAPS
* reordered card_label calculation
* fill default-values
* return the used device number
* move v4l2_loopback_config to a separate header
* move IDR declaration to a better place.
* drop devptr from v4l2_loopback_add
* use "int" instead of "bool" for the public interface
* now that exclusive_caps are int and can be negative, use that to ask for the default
* use "err" instead of "ret"
* implement /dev/v4l2loopback to dynamically create/remove devices
* use a mutex to prevent concurrent access to the /dev/v4l2loopback device
* check whether the device is currently open before closing it
* v4l2_loopback_config.card_label now has a fixed size (32 bytes)
* only return the device-number if device_add was successfull
* added QUERY ioctl
* sample application to add/delete/query devices on the fly
* indentation
* moved DEFINE_IDR/MUTEX *again*
* "every" -> "each"
* show default values in "modinfo"
* Makefile for utils/
* don't assume that IDR matches the device-number
* less verbose
* print perror() if query fails
* explicitely return ENOSYS for invalid ioctls
* use "break" instead of "goto"
* return EINVAL by default for valid ioctls
* copy data from userspace instead of casting away
* note that we need two device numbers
* Add example udev rules.
