A few weeks ago, we described an issue with TouchXPRT’s Create Slideshow test. On some systems, this test would take longer than expected to complete due to the output video not rendering correctly. Since then, we released TouchXPRT 2016 CP2, which includes a check that verifies the output and reports an error if there’s a problem.
It took a lot of detective work, but I’m happy to say that we’ve been able to resolve this issue. We had to make a couple of changes. First, we changed the pixel format in which the photo content is read from GUID_WICPixelFormat32bppPBGRA to GUID_WICPixelFormat32bppBGR. Second, we changed the media format of the input into the video converter from MFVideoFormat_ARGB32 to MFVideoFormat_RGB32.
After making these changes, the Create Slideshow test ran in the expected amount of time, and rendered the output video correctly.
In our testing so far, results have not changed noticeably. However, we’re continuing to test. We want to be sure that the updated build is stable and that results are comparable to earlier TouchXPRT CPs. We’ll then release it to the community.
Here’s looking forward to the release of TouchXPRT 2016 to the world at large!
