The original implementation of pac_find_sof() does not always find the Start Of Frame (SOF) marker. Replace it with a state machine based design. Acked-by:

gspca: Don't resubmit error status URB's when suspending Signed-off-by:
-
Hans de Goede authored
The gscpa core was not resubmitting URB's when the URB status was an error, this means we will loose URB's (potentially all stopping the stream) in case of sporadic USB issues. I've seen this with an Aiptek stv0680 based PenCam connected through an USB 2.0 hub. Signed-off-by:

This patch adds a new subdriver to gspca supporting cams with the stv0680 bridge (replacing the old in kernel v4l1 driver). Many thanks to Hans Verkuil for providing me with one of the 2 cams used in testing this new sub driver. Signed-off-by:

gspca w9968cf: slight tweak to vstart and hstart to get rid of black borders in 640x480 mode. Signed-off-by:
-
Hans de Goede authored
gspca w9968cf: Add support for JPEG compression, this enables much higher framerates at 320x240 / 352x288 and also allows for 640x480 mode for cams which can do this. The w9968cf uses planar JPEG, which libv4l until now did not support, so this requires atleast version 0.6.3 of libv4l. And something important I forgot to mention in my earlier w9968cf commits: Many thanks to Hans Verkuil for giving me a w9968cf based cam, which has allowed me to develop the gspca w9968cf support.

gspca-w9968cf: Don't add an extra packet to the buffer after the EOF, this makes the frame data size bigger then it should be which makes gstreamer discard it. This patch also fixes an unrelated compiler warning. Signed-off-by:

Cache sensor regs to avoid unnecessary slow i2c reads / writes, this speeds up sd_start a bit with most bridges and a lot (from 5 seconds down to 0.3 seconds) with W996xCF cams, as this avoids very slow bit bang IO over USB i2c reads. Signed-off-by:

This patch adds support to gspca for the Winbond W9967CF and W9968CF camera's. This is mostly a port of the existing v4l1 driver to gspca (making it v4l2). But this also features fixes to the bitbanging i2c code (send a nack not an ack after reading the last byte of a transfer), which gets rid of the weird errors which were being seen there, and of the smbus_refresh() hack to get around these errors. Also the vstart settings have been tweaked to work with different frequency filter settings. Signed-off-by:

If the I2C device provides an interrupt it is registered and the standard is updated via interrupts rather than polling. Since I2C communication is needed, the interrupt handler fires off a work which will check the new standard, and store it in the internal structure. To handle mutual exclusion a mutex is introduced.

Support for settings the input standard of the ADV7180. When the input standard is set there is no use to ask the chip for standard, therefore it is cached in the driver. Signed-off-by:

This patch adds support to the ADV7180 driver to check the input status. Since the status is held in the same register as the input standard a small restructuring of the code is done to reuse the code for reading the register Signed-off-by:

V4L/DVB (13168): Add support for Asus Europa Hybrid DVB-T card (SAA7134 SubVendor ID: 0x1043 Device ID: 0x4847) Adds the device IDs and driver linking to allow the Asus Europa DVB-T card to operate with these drivers. The device has a SAA7134 chipset with a TD1316 Hybrid Tuner. All inputs work on the card including switching between DVB-T and Analogue TV, there is also no IR with this card.

The definition of tvaudio_tuner_ops initializes the s_tuner field twice. It appears that the second case should initialize the g_tuner field. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by:

When the image size (bytesperline*height) is not multiple of PAGE_SIZE, v4l2 rounded the required buffer size to be multiple of PAGE_SIZE. This prevented user space to store images directly into userptr buffers which were not multiple of PAGE_SIZE. This constraint is removed. The start address is still assumed to be required page-aligned, ie., when v4l2 allocates mmap buffers, the offset between different buffers is page-aligned. Signed-off-by:

DVBS2API introduced two new ioctls that allows changing/getting details about newer video standards like DVB-S2 and ISDB-T. There are lots of thing to do in this chapter, but, for now, just add a session there, in order to allow make to not complain about undefined symbol. With this patch, all ioctls at the frontend.h API were somehow documented. Signed-off-by: -
Mauro Carvalho Chehab authored
We'll need to add the documentation for FE_[GET|SET]_PROPERTY that is not specific to isdb-t. Instead of doing it at frontend.xml, it is better to have a separate session for it. Also, isdbt.xml assumes that those ioctls were already introduced, and documents several exisiting properties. So, better to just rename it and add the documentation for it, together with each existing property there. Signed-off-by: -

The default streaming control timeout was found by Ondrej Zary to be too low for some Logitech webcams. With kernel 2.6.22 and newer they would timeout during initialization unles the audio function was initialized before the video function. Add a module parameter to set the streaming control timeout and increase the default value from 1000ms to 3000ms to fix the above problem. Thanks to Ondrej Zary for investigating the issue and providing an initial patch. Signed-off-by:

This patch sets stream->urb_size as psize*npackets before calling uvc_alloc_urb_buffers, which may fix a possible failure of usb_buffer_free in case usb_buffer_alloc returns NULL. The patch is based on the ideas below: 1,If usb_buffer_alloc can't allocate a buffer sucessfully, uvc_free_urb_buffers will be called to free the allocated buffers, and stream->urb_size is required to be passed to usb_buffer_free; 2,uvc_free_urb_buffers can reset stream->urb_size. This patch is against linux-v2.6.31-next-20090926. Signed-off-by:
