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.

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>

From: Hans Verkuil <hverkuil@xs4all.nl> Adds the cx2341x.c module that handles the programming of the Conexant cx23415/6 MPEG encoder chip used by cx88-blackbird, pvrusb2 and ivtv. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
