Xash3D engine supported movie playback for a long time, but it utilizes Video for Windows API, which has downsides from obviously being closed source and Windows exclusive and requiring the user to install third-party software. It also sometimes just outright doesn't work for an unknown reason. This time I have implemented video player using ffmpeg to the Xash3D FWGS engine, which was in the plan for a whopping eight years already. The obvious improvement of using ffmpeg is a wide variety of codecs. It successfully worked with movie intros from Half-Life, Opposing Force and Paranoia mod. But very VFW specific internal engine logic, bites me. Instead of normal playback, the engine tracks frames by itself and tries to seek over the movie stream. Seeking itself is harmless, but it makes playback very suboptimal, and some frames may be lost, which doesn't make the decoder happy. A random Bink file my friend found for me works, but it absolutely fails on VP9 streams, from refusing playing them at all or just showing random artifacts. The second video showing artifacts on VP9 stream (random WebM video, epilepsy warning): idtech.space/media/d387c7f54dcf7β¦
