by the application.

Wait until the audio is stable for at least 400ms before starting the
mpeg encoder.

Mute/Unmute the audio when starting/stopping the mpeg encoder.

Stop the mpeg encoder when changing parameters and when changing tuner
frequency.

Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of
whether or not the mpeg2 encoder is active.

Ian Armstrong [Mon, 5 Nov 2007 17:27:09 +0000 (14:27 -0300)]
V4L/DVB (6717): ivtv: Initial merge of video48 yuv handling into the IVTV_IOC_DMA_FRAME framework

Previously, all yuv data written to /dev/video48 had only basic support with
no double buffering to avoid display tearing.

With this patch, yuv frames written to video48 are now handled by the existing
IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to
avoid tearing, and honour scaling mode & field order options. Unlike the
proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the
V4L2 API.

Due to mpeg & yuv output restrictions being different, their V4L2 output
controls have been separated. To control the yuv output, the V4L2 calls must
be done via video48.

If the ivtvfb module is loaded, there will be one side effect to this merge.
The yuv output window will be constrained to the visible framebuffer area. In
the event that a virtual framebuffer size is being used, the limit to the
output size will be the virtual dimensions, but only the portion that falls
within the currently visible area of the framebuffer will be shown.

Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720
pixels wide. However the height must only be padded up the nearest multiple
of 32. This would mean an image of 102 lines must be padded to 128. As long
as the true source image size is given, the padding will not be visible in
the final output.
