Hi all. I’ve recently run into some issues with the WMF player and am curious if others have seen this as well, and hopefully may have some ideas for fixes…
I have a kiosk app with some moderate video playback needs. Most of the time I’m playing only a single HD video, though there is a moment where I’m playing 9 thumbnails simultaneously (all HD – the resolution isn’t necessary but the GPU load/bandwidth in GPU-Z seems fine handling this on a GTX1080). All of the videos (these + more, about 36 total) are preloaded at app launch, and the VRAM is at about 3.5GB (out of 8GB).
My issue is that on occasion, when either playing a video, or seeking to a new position (sometimes forward, sometimes behind the current position) and playing, the video (and the whole app, I think) seems to hang for a few seconds. It’s very inconsistent and hard to reproduce, but it seems like it may occur when the video hasn’t been played in a while (and other videos have), so maybe whatever cache/buffer is created by WMF or the WMF block is stale, or that given video is no longer cached, and part of that video needs to get loaded again? I haven’t dug into the internals of the block to understand what’s going on
Anyway, I’m hoping for some tips or tricks here. I would love to not switch to loading these videos on demand, or deal with swapping out the video player entirely . Oh, and this is running on Windows 7 Pro, 64bit, VS2015.
Thanks for any leads!
