Now works with both NTSC and PAL. Tested with CC/XDS for NTSC and teletext/WSS for PAL. The start lines were wrong, the WSS signal wasn't captured and there was no difference between NTSC and PAL w.r.t. the count[] values so NTSC returned way too many lines. Signed-off-by:

The vb2 framework knows if streaming is in progress, no need to use a separate field for that. Signed-off-by:
-
Hans Verkuil authored
The width, height and field values are core fields since both vbi, video and blackbird use the same video input. Move those fields to the correct struct. Also fix the field checks in the try_fmt functions: add V4L2_FIELD_SEQ_BT/TB support and map incorrect field values to a correct field value instead of returning an error. Signed-off-by:

There is no reason to dump the sram code to the kernel log when you stop streaming. Remove those calls to cx88_sram_channel_dump. Signed-off-by:

The timeout is way too small. Especially complicated command like CX2341X_ENC_STOP_CAPTURE takes much more time than 10 ms. Increase the timeout to 1 second, just as ivtv does (the cx88-blackbird has the same IP core for MPEG compression as ivtv). This solves a nasty issue where STOP_CAPTURE would timeout and the mailbox is left in a busy state, making it impossible to start streaming a second time without reloading the driver first.

drivers/media/pci/cx88/cx88-blackbird.c:476:25: warning: cast to restricted __le32 Signed-off-by:
-
Hans Verkuil authored
As usual, this patch is very large due to the fact that half a vb2 conversion isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and video the changes are all over. What made this more difficult was the peculiar way the risc program was setup. The driver allowed for running out of buffers in which case the DMA would stop and restart when the next buffer was queued. There was also a complicated timeout system for when buffers weren't filled. This was replaced by a much simpler scheme where there is always one buffer around and the DMA will just cycle that buffer until a new buffer is queued. In that case the previous buffer will be chained to the new buffer. An interrupt is generated at the start of the new buffer telling the driver that the previous buffer can be passed on to userspace. Much simpler and more robust. Signed-off-by:

This list is only used if the width, height and/or format of a buffer has changed, but that can never happen. Remove it and all associated code. Signed-off-by:

Hans Verkuil authored
This is a duplicate of dev->fmt and can be removed. As a consequence a lot of tests that check if the format has changed midstream can be removed as well: the format cannot change midstream, so this is a bogus check. Signed-off-by:

This patches fixes an ancient bug in the dvb_usb_af9005 driver, which has been reported at least in the following threads: https://lkml.org/lkml/2009/2/4/350 https://lkml.org/lkml/2014/9/18/558 If the driver is compiled in without any IR support (neither DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in af9005_usb_module_init() return pointers != NULL although the IR symbols are not available.

Until anyone who still has this old hardware steps up an does the conversion, fix it by not calling the symbol_request calls if the driver is compiled in without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE). Due to the IR related pointers beeing NULL by default, IR support will then be disabled. The downside of this solution is, that it will no longer be possible to compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in. Please note that this patch has NOT been tested with all possible cases. I don't have the hardware and could only verify that it fixes the reported bug. Reported-by:
