printz Posted April 5, 2015 So I loaded a demo saying "-timedemo crap" and recorded it saying "-viddump video.mkv". I have the "oggenc2.exe", "x264.exe" and "mkvmerge.exe" programs copied into the PrBoom+ folder. However, at the end of the demo, no "video.mkv" appears and "video_stderr.txt" says "x264 [error]: Unknown muxer `mp4'" while "stdout.txt" keeps saying "I_CaptureFrame: error writing videopipe.". What should I do to make PrBoom+ video work? I'm on Windows 8.1 64-bit. 0 Share this post Link to post
