2009-06-14ivtv/cx18: fix regression: class controls are no longer seenMauro Carvalho Chehab
From: Hans Verkuil <hverkuil@xs4all.nl> A previous change (v4l2-common: remove v4l2_ctrl_query_fill_std) broke the handling of class controls in VIDIOC_QUERYCTRL. The MPEG class control was broken for all drivers that use the cx2341x module and the USER class control was broken for ivtv and cx18. This change adds back proper class control support. Priority: high Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-02-21v4l2-common: remove v4l2_ctrl_query_fill_stdHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had. It doesn't add anything valuable that cannot be expressed equally well with v4l2_ctrl_query_fill and only adds overhead. Replace it with v4l2_ctrl_query_fill() everywhere it is used and remove it from v4l2_common.c. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-02-13v4l2-common: add comments warning that about the sort orderHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Control arrays as are used with v4l2_ctrl_next must be sorted from low to high. Add a comment at the top of all such arrays to warn about this. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-02-13cx2341x: fixed bug causing several audio controls to be no longer listedHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The cx2341x_mpeg_ctrls array must be ordered by control ID. I know that this is bad design, but for now I will just fix this bug and revisit it when all drivers have moved to v4l2_device/v4l2_subdev, since that will allow me to do greatly improve control handling.

2009-01-03cx18, cx2341x: Fix bugs in cx18 AC3 control and comply with V4L2 specAndy Walls
From: Andy Walls <awalls@radix.net> Fix bugs in the cx18 AC3 control implementation that would have affected ivtv and other drivers via the cx2341x module. Bring AC3 controls behavior into comliance with V4L2 specification. Thanks to Hans Verkuil for reviewing the previous patch and pointing out the problems.

2009-01-01cx18, cx2341x, ivtv: Add AC-3 audio encoding control to cx18Andy Walls
From: Andy Walls <awalls@radix.net> Initial addition of controls to set AC-3 audio encoding for the CX23418 - it does not work yet due to firmware or cx18 driver issues. This change affects the common cx2341x and ivtv modules due to shared structures and common functions. Priority: normal Signed-off-by: Andy Walls <awalls@radix.net>
2008-08-08v4l2: extend MPEG Encoding API with AVC and AACHans Verkuil
From: Janne Grunau <j@jannau.net> Adds Advanced Audio Coding (AAC) and MPEG-4 Advanced Video Coding (AVC/H.264) as audio/video codecs to the extended controls API. Updates cx2341x driver to the new values. Priority: normal Signed-off-by: Janne Grunau <j@jannau.net> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-07-17ivtv/cx18: ensure the default control values are correctHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> For several MPEG controls and the volume control the default as returned by VIDIOC_QUERYCTRL was incorrect and did not match the actual initial value. This is now fixed for cx18 and ivtv. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-07-08v4l-dvb: remove support for kernels < 2.6.0Hans Verkuil

2007-08-21cx2341x: some controls should not be changed while the device is busy.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-21Cleanup: remove linux/moduleparam.h from drivers/media filesMauro Carvalho Chehab

2007-02-20Split VIDEO_MUTE into MUTE and MUTE_YUVHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It is bad practice to basically combine two functions (mute on/off and precise video mute YUV value) in one control. Split them. Also ensure that the default mute value is black. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2007-02-18Add support for three new MPEG controls.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Added V4L2_CID_MPEG_AUDIO_MUTE, V4L2_CID_MPEG_VIDEO_MUTE and V4L2_CID_MPEG_CX2341X_STREAM_INSERT_NAV_PACKETS controls together with their implementation in the cx2341x module. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-12-19Removed unimplemented cx2341x API commandsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The commands CX2341X_DEC_SET_AUDIO_OUTPUT, CX2341X_DEC_SET_AV_DELAY and CX2341X_ENC_SET_3_2_PULLDOWN are not implemented in the Conexant firmware. So these commands are removed. This also means that the V4L2_CID_MPEG_VIDEO_PULLDOWN control in cx2341x.c and pvrusb2-hdw.c is removed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-12-18LOG_STATUS should show the real temporal filter value.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The temporal filter is forced off when scaling. The VIDIOC_LOG_STATUS handler still showed the old temporal filter. It is now consistent with the real temporal filter value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-12-18Force temporal filter to 0 when scaling to prevent ghosting.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Change the code to unconditionally turn off the temporal filter when scaling. If the window is not full screen the filter will introduce a nasty ghosting effect. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-08-28Better temporal filter handling.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Adjust temporal filter if necessary. The problem with the temporal filter is that it works well with full resolution capturing, but not when the capture window is scaled (the filter introduces a ghosting effect). So if the capture window changed, and there is no updated filter value, then the filter is set depending on whether the new window is full resolution or not. For full resolution a setting of 8 really improves the video quality, especially if the original video quality is suboptimal. Also report VBI Format in VIDIOC_LOG_STATUS, it was missing.

2006-06-26Pass an explicit log prefix to cx2341x_log_statusHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> A card number is not unique enough. Instead, let the caller specify the prefix of the status messages. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2006-06-24Add V4L2_CID_MPEG_STREAM_VBI_FMT controlHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in an MPEG stream. Currently only one format is supported: the format designed for the ivtv driver. This should be extended with new standard formats (such as defined for DVB) in the future. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-06-21CX2341X port was always set to 'memory', but 'streaming' is also possibleHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> ivtv uses the memory (DMA) interface with the CX2341X, while pvrusb2 and cx88-blackbird use the streaming interface. This setting is now selectable by the driver. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2006-06-19Disable bitrate_mode when encoding mpeg-1.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> MPEG-1 always uses CBR, so make the BITRATE_MODE control inactive. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
