2007-02-21V4L/DVB (5089): Pvrusb2: V4L EXT_CTRLS fixupMike Isely
Attempts to enumerate or operate on a group of EXT_CTRLS where the group size is zero is OK; don't fail on such operations. At least one application uses this to probe for the existence of this API so let it succeed. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-21V4L/DVB (5083): Pvrusb2: Remove automodeswitch controlMike Isely
The automodeswitch control was a feature that enable automatic radio / tv switching based on the selected frequency. However since frequency ranges can overlap and also since apparently in some cases it's possible for the same frequency range to be both tv and radio in a specific region, then this feature can't safely work. So it's removed. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-02-21V4L/DVB (5077): Bttv cropping supportMichael Schimek
Adds the missing VIDIOC_CROPCAP, G_CROP and S_CROP ioctls, permitting applications to capture or overlay a subsection of the picture or to extend the capture window beyond active video, into the VBI area and the horizontal blanking. VBI capturing can start and end on any line, including the picture area, and apps can capture different lines of each field and single fields. For compatibility with existing applications, the open() function resets the cropping and VBI capturing parameters and a VIDIOC_S_CROP call is necessary to actually enable cropping. Regrettably in PAL-M, PAL-N, PAL-Nc and NTSC-JP mode the maximum image width will increase from 640 and 768 to 747 and 923 pixels respectively. Like the VBI changes however, this should only affect applications which depend on former driver limitations, such as never getting more than 640 pixels regardless of the requested width. Also, new freedoms require additional checks for conflicts and some applications may not expect an EBUSY error from the VIDIOC_QBUF and VIDIOCMCAPTURE ioctls. These errors should be rare though. So far, the patch has been tested on a UP machine with a bt878 in PAL- BGHI and NTSC-M mode using xawtv, tvtime, mplayer/mencoder, zapping/ libzvbi and these tools: http://zapping.sf.net/bttv-crop-test.tar.bz2 I'd be grateful about comments or bug reports.

2007-02-21V4L/DVB (5053): Pvrusb2: Change default volume to something saneMike Isely
The default volume of 65535 is too high. Make is something smaller. Note that this _only_ changes the default value. Specifically, there are no scaling or other more intrusive changes here. I'm just sick of constantly having to reduce the volume every time I plug in and test the device! (And unfortunately we can't do a better fix like scaling the volume so that 65535 makes sense because doing so will screw up any app - like MythTV - which expects the old scaling.) Too bad V4L controls don't have better defined ranges. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5052): Pvrusb2: Remove stream claiming hack from /dev/radioMike Isely
Trying to temporarily check that the stream is not claimed during open of the radio device is at best a race condition. What's to stop another app from claiming the stream anyway the instant after the check is done? The implementation for this was dicey anyway. So it's removed. The only "price" for this is that if /dev/radioX is opened while streaming video, then the video stream is just going to switch to radio mode anyway. If a user does this, he gets what he expects...

2007-02-21V4L/DVB (5047): Pvrusb2: Fix tuning calculation when in radio modeMike Isely

2007-02-21V4L/DVB (5039): Pvrusb2: Implement /dev/radioXPantelis Koukousoulas
The "main" V4L2 interface patch. This is yet very incomplete, incorrect and probably inappropriate for inclusion as-is, but at least with this I 'm able to tune and play radio through a V4L2 program (pvr-radio.c, a "thumb" version of ivtv-radio.c with just the essentials). Therefore, it kinda gives an idea of what is needed to support this, hm, interface (partly used also by e.g., kradio). Please point out any mistakes on this code. I 'm sure I 'm messing up some struct initialization somewhere but currently I 'm too lazy to actually think this through until I complete the functionality (e.g., handle the VIDIOC_S_STD, ENUMINPUT, etc ioctls appropriately).

2007-02-21V4L/DVB (5038): Pvrusb2: Implement stream claim checking functionPantelis Koukousoulas
Add (and expose) a new function, pvr2_channel_check_stream_no_lock(), in pvrusb2-context.c. This is hopefully the last V4L2 interface related patch to change anything outside pvrusb2-v4l2.c. We need this to implement the open() for the radio device. The reason is that within the *enter_context() section of open() we need to ensure nobody is streaming and if we cannot, we should cleanup after ourselves and return -EBUSY. We cannot just use claim_stream() because: 1) That would cause a deadlock trying to re-acquire the context lock 2) We only need to ensure that nobody is streaming. We don't need to actually acquire the stream. Again, this is a kinda ugly patch. Feel free to improve.

2007-02-21V4L/DVB (5037): Pvrusb2: Implement multiple minor device number handlingPantelis Koukousoulas
This is the first patch in preparation of the V4L2/IVTV radio interface. It does away with the assumption of only one minor per device. It also adds a file to show the radio minor as well. This can be useful for a program like pvr-radio.c (when it grows up), since this way it can search for the minor of the /dev/radioX device it opened and use the video minor of the same driver instance to get to the actual stream. The implementation looks kinda ugly. Feel free to improve (that is the reason behind separate patches anyway).

2007-02-21V4L/DVB (5036): Pvrusb2: Fix for min/max control value checkingPantelis Koukousoulas
In the previous patch we exploited the get_{min,max}_value facility to adjust min/max allowable frequencies on the fly, depending on tuner mode. Unfortunately, this facility was not used inside the *sym_to_val() function that translates what we echo to sysfs, which means we got an -ERANGE despite asking for a frequency between what we read to be min/max. This patch corrects this small omission.

2007-02-21V4L/DVB (5035): Pvrusb2: Enable radio mode round #2Pantelis Koukousoulas
This is the logic that: a) Ensures /sys/class/pvrusb2/sn-*/ctl_frequency/{max,min}_val are "automagically" reset to sane values on each mode change. b) Allows tuning to a radio frequency by something like: echo `perl -e "print int(94.9*16000 + 0.5)"` \ > /sys/class/pvrusb2/sn-*/ctl_input/cur_val The trick was to take advantage of the already existing .get_{min,max}_value function pointers in pvr2_ctrl, to "dynamically override" the hardcoded values for min/max frequency at runtime. For a moment I thought to dispose of the hardcoded MIN/MAX_FREQ and use the hirange/lowrange fields of the v4l2_tuner struct instead, but then I see that tuner-core.c kinda hardcodes these as well, so I decided to not bother.

2007-02-21V4L/DVB (5034): Pvrusb2: Enable radio mode round #1Pantelis Koukousoulas
This is the logic that supports switching modes via e.g., echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val. To do the mode switching we need to: a) broadcast AUDC_SET_RADIO and b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is done by adding a new pvr2_i2c_op and having it trigger on input change, the second by adding this command in pvr2_encoder_start() and requesting an encoder restart on input change by setting stale_subsys_mask appropriately. The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode switching this way (on input change) is due to Mike Isely. Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but I think this can be traced to a cornell student being the first to implement radio support in ivtv "as a different standard". I think the rest just evolved from there (it 's in the ivtv ML archives).
