From 1f93daa4570eb74f94fff23dbe9fb4b29af53291 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 16 Oct 2007 08:21:46 +0200 Subject: ivtv: ivtv yuv stream handling change From: Ian Armstrong Currently the yuv output stream buffer is divided into blocks whose size depend on the broadcast standard selected during the driver init phase. However, the standard can be changed after the init phase. This effectively breaks the yuv output stream handler, since it relies on the different yuv planes being block aligned. This patch changes the setup, so that the block size is always the same. The decoder dma function has been modified to cope with the fact that the second yuv plane may no longer be block aligned. The start of the yuv frame must still be at the beginning of a block, so the stream write function has also been modified to ensure this is always true. Also, the stream write function will now initiate a yuv dma transfer as soon as a full frame is ready. It will not wait until the current write request has completed, or the stream buffer becomes full.

Should there be a change in any single parameter, it will update the associated display registers to ensure everything is displayed correctly. The existing check also looks at the field order for the video. This is not required, since field reversal does not require any display register changes. This patch removes the field order from the check.

Given that it can affect how a new frame is displayed, it was a bit stupid running it after the frame was already visible. A few stray interlace related variables which were linked to individual frames have now been moved into the yuv_frame_info struct. This means that all variables linked to a specific frame are in the same place & not scattered. Minor code reformatting in areas touched by the above changes.

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.
