[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31Z

Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer for common use, and change its type to u64 in order to handling y2038 problem. This patch also includes all device drivers' changes related to this restructuring.

[media] vb2: drop v4l2_format argument from queue_setup

2015-12-18T15:48:19Z

The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dv-timings: add new arg to v4l2_match_dv_timings

2015-12-03T13:26:14Z

Add the new match_reduced_fps argument to v4l2_match_dv_timings(). Depending on the situation you may or may not desire to match the reduced_fps flag. Typically only HDMI transmitters will need to check for this flag. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: add support for reduced frame rate in video capture

2015-11-17T17:06:22Z

With this patch, vivid capture thread can now generate a video with frame rate reduced by a factor of 1000 / 1001. This option can be selected using a control Reduced Framerate from gui. Signed-off-by: Prashant Laddha Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid-capture: add control for reduced frame rate

2015-11-17T17:06:00Z

A boolean control Reduced Framerate is added to vivid controls for controlling the reduced fps option for vivid capture from gui. Signed-off-by: Prashant Laddha Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: add support for reduced fps in video out

2015-11-17T17:05:40Z

If reduced fps flag is set then check if other necessary conditions are true for the given bt timing. If yes, then reduce the frame rate. For vivid transmitter, timeperframe_vid_out controls the frame rate. Adjusting the timeperframe_vid_out by scaling down pixel clock by factor of 1000 / 1001.

[media] vivid: fix compliance error

2015-11-17T16:34:23Z

If vivid is loaded with the no_error_inj=1 option, then v4l2-compliance will fail for the video and vbi output nodes because the vivid control class has no controls. Don't add the control class for video and vbi output if no_error_inj is true. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media/vivid-osd: fix info leak in ioctl

2015-10-20T17:34:29Z

The vivid_fb_ioctl() code fails to initialize the 16 _reserved bytes of struct fb_vblank after the ->hcount member. Add an explicit memset(0) before filling the structure to avoid the info leak. Signed-off-by: Salva Peiró Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: Add an option to configure the maximum number of devices

2015-10-03T14:36:24Z

The vivid driver currently has a hard-coded limit of 64 devices, however there's nothing that prevents the creation of even more devices. This commit adds a new driver option (which defaults to 64) to allow this maximum number to be configurable. Signed-off-by: Ezequiel Garcia Signed-off-by: Mauro Carvalho Chehab
