And screenshot of FTEQW playing a video:
The extension: {"FTE_MEDIA_ROQ"}, //playfilm command supports q3 roq filesI tossed zombies.roq into c:\quake1\id1 folder and did "playfilm zombies.roq" into the console and viola!
Try it yourself:
Download this zombies.roq (download - 17 MB) and do playfilm zombies.roq
No there is no sound in the zombies.roq file because I didn't think of the sound. So no, no sound should play.
