[media] vivid: use new v4l2-rect.h header

2016-04-20T19:13:31+00:00

The v4l2_rect helper functions have been moved to include/media/v4l2-rect.h. Use this new header, dropping the functions from vivid. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: fix smatch errors

2016-04-20T18:47:33+00:00

The smatch utility got really confused about the grp % 22 code. Rewrote it so it now understands that there really isn't a buffer overwrite. vivid-rds-gen.c:82 vivid_rds_generate() error: buffer overflow 'rds->psname' 9 <= 43 vivid-rds-gen.c:83 vivid_rds_generate() error: buffer overflow 'rds->psname' 9 <= 42 vivid-rds-gen.c:89 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 84 vivid-rds-gen.c:90 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 85 vivid-rds-gen.c:92 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 86 vivid-rds-gen.c:93 vivid_rds_generate() error: buffer overflow 'rds->radiotext' 65 <= 87 Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: support new multiplanar YUV formats

2016-03-03T10:48:31+00:00

Add support for the new YUV422M, YVU422M, YUV444M and YVU444M formats. This allows applications to check their support for these formats. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] media: platform: vivid: vivid-osd: Remove unnecessary cast to kfree

2016-02-10T11:29:02+00:00

Remove an unnecassary cast in the argument to kfree. Found using Coccinelle. The semantic patch used to find this is as follows: // @@ type T; expression *f; @@ - kfree((T *)(f)); + kfree(f); // Signed-off-by: Amitoj Kaur Chawla Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] vivid: fix broken Bayer text rendering

2016-02-01T10:16:28+00:00

Sometimes when a Bayer pixelformat is selected the rendering of the OSD text by vivid was all wrong: every other line of the text was shifted by half the width or more. It turned out that to render Bayer formats the interleaved boolean is set to true in the tpg. This mode indicates a semi-biplanar mode where two interleaved planes are used to render the frame. From outside the tpg it looks like a single plane, but internally it is two planes. However, in the tpg_s_bytesperline() function the interleaved bool wasn't checked and only the bytesperline value for plane 0 was updated. But for the interleaved mode the same value has to be copied to bytesperline[1] as well. The effect was that whatever old value was left in bytesperline[1] was used, which caused all sorts of weird and seemingly unpredictable shifts.

[media] media: videobuf2: Move timestamp to vb2_buffer

2015-12-18T15:53:31+00:00

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

2015-12-18T15:48:19+00:00

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

2015-12-03T13:26:14+00:00

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
