<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"> I have a usage case of libva: I read camera frame to a VASurface (VA_FOURCC_YUY2 format),
<o:p></o:p></p>
<p class="MsoNormal">translate the format from VA_FOURCC_YUY2 to VA_FOURCC_NV12 and then show VASurface content
<o:p></o:p></p>
<p class="MsoNormal">to screen. The code of translating format is as below:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> VAImage nv12_image;<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in">va_status = vaDeriveImage(va_dpy, nv12_surface_id, &nv12_image);<o:p></o:p></p>
<p class="MsoNormal"> va_status = vaGetImage (va_dpy, gray_bgra_surface_id, 0, 0, width, height, nv12_image.image_id);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> It fails on vaGetImage with return value VA_STATUS_ERROR_SURFACE_BUSY. I dig into<o:p></o:p></p>
<p class="MsoNormal">intel-driver, and find it returns on the this line of i965_GetImage():<o:p></o:p></p>
<p class="MsoNormal"> if (is_image_busy(i965, obj_image))<o:p></o:p></p>
<p class="MsoNormal"> return VA_STATUS_ERROR_SURFACE_BUSY;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Could you find a way to solve this problem? Because it’s the most convenient way I know translating<o:p></o:p></p>
<p class="MsoNormal">one format VASurface to another.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
