Blank screens

[theavidavidemuxuser]

I've been using Avidemux as my primary video muxer for a few years now, but the latest nightly build for some reason does not display any video, only a black screen. Could anyone help me out on this? I haven't been able to find anything.[attach id=5087]am.png

Are you on Windows? The r241212 cross-build ("win64") should be fine, later VC++ (native) builds ("vsWin64") may have substantial issues.

If you get a black video preview in the main window with r241212, please provide admlog.txt (%localappdata%\avidemux\admlog.txt).

How do I provide that?

Please ZIP-compress the file and attach it to your reply. Alternatively, you may use a hoster like pastebin.com if you wish so.

Thank you for the log. In general, it would have been fine to anonymize it, i.e. consistently replace all paths with corresponding placeholders to make it reasonably safe to publish it, unless the very presence of timestamps in the log may be a issue for you. The problem is here:

We don't detect that we cannot use DirectX (in Avidemux inaccurately called "DXVA2") renderer with very recent Intel HW like on your system. You should enable OpenGL in Avidemux and switch "Video Display" from "DXVA2" to "OpenGL" in Edit -> Preferences -> Display.
