Change the pitch of the RGB format. |

Change the pitch of the RGB format.
By applying this patch (correct the RGB pitch), the output image show up, but the whole image are reddish.

Created attachment 76302 [details] Some code change to take the fastscale flag and use i965_image_processing to convert NV12 to RGM into swap buffer. Hi, I need some image format conversion features to test difference performance. Anyway, with staging-20130205 on both libva and intel-va-driver. I modified some code to use the i965_image_processing to convert NV12 to RGB but the output is corrupted. Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller [8086:0152] (rev 08) OS : Fedora 18 Kernel : 3.7.4-204.fc18.i686 libva : staging-20130205 intel-va-driver : staging-20130205 with some patch to enable NV12 to RGB with i965_image_processing. vaapi-mplayer : latest screen info : 1920x1200@60 With the attached patch apply to intel-va-driver. Now when calling "./mplayer -vo vaapi:scaling=fast -va vaapi <video clip>" it will go to the path that use i965_image_processing to convert the NV12 to RGB into swap buffer and display it. Anyway, the image is corrupted. Using the normal command are fine, "mplayer -vo vaapi -vaapi <video>".
