VideoWidget fails to load video files on the Windows client. The widget remains in VideoState.NONE, with position and duration equal to 0. ON_ERROR fires before ON_LOAD or ON_PLAY.

The log reports “VideoWidget: Can't load video stream”.

We tested MP4/H.264 Main, MP4/H.264 Baseline and WebM/VP8 at 1920×1080, 30 FPS. Loading failed from the mod PBO, from $profile: after automatic copying, and from a relative video/ folder beside the executable.

The copied files match the originals. Windows Media Foundation successfully creates a source reader for these files outside DayZ. Unload() and error callbacks are implemented; the issue occurs on the first playback attempt.

• Run the Windows Experimental client with a client-side mod that creates a VideoWidget.

• Copy a test video to $profile:VideoTest/test.mp4.

• Register ON_LOAD, ON_PLAY and ON_ERROR callbacks before loading.

• Call Load("$profile:VideoTest/test.mp4", false, 0) and Play().

• Observe ON_ERROR, state NONE and duration 0. No video appears.

• Repeat with WebM/VP8 or a relative video/test.mp4 path. Our tests produce the same failure.

The video should load and play, triggering ON_LOAD and ON_PLAY.

Please clarify the supported containers/codecs and paths for VideoWidget on Windows in 1.30, and whether additional native error diagnostics can be enabled.
