Looper Posted April 10, 2012 Hello. I made a 4-player built nomonsters run through the whole doom2. I hope you enjoy it even if it's nomonsters. As Andy O. said, it would be too much of a headache to do a co-op built run with monsters around. I didn't think much about those fast turns etc. so it's probably little confusing demo, but it presents some new tricks. Notice that it doesn't show the time nor total time in intermission screen because 4 players, but with prboom+ that's not a problem. I hope you enjoy.

Memfis Posted April 10, 2012 Awesome! So many cool tricks. Funny how players shoot each other, and thingrunning on map31 is beyond hilarious. After map29, I was like :oooo I guess I'll have to watch this a few times to fully understand everything. :) Would be cool if someone made a video out of this with switching cameras to show the most important parts. 0 Share this post Link to post
entryway Posted April 10, 2012 ha-ha! Make d2qd .cam file for better understanding what's happening there. Or make split screen youtube video with all four players. 0 Share this post Link to post
Looper Posted April 10, 2012 I would upload them to youtube but if I use fraps to capture it, all the 4 demos desync about 1 second every 1 minute :( Is there in-game built lmp to avi converter (I remember seeing a thread about that)? Maybe that doesn't desync like fraps so it would be easy to fit four videos in one video :) How does that .cam thing work? 0 Share this post Link to post

Some time ago I added support for Donner's d2dq cam.cam file, but not commited it. If somebody need it, I'll commit. I do not know any tools for creating cam files except hex editor, but it should not be hard to write something simple. 0 Share this post Link to post
abyrvalg Posted April 11, 2012 very interesting demo, had to watch it few times in slowmo, constantly f12ing and pausing to understand what's happening. Liked maps 29,30,31 the most, great trickery :) Perhaps a 2-way coop run with monsters is buildable, what do you think? Or would it still be the hell to manipulate things? 0 Share this post Link to post
dew Posted April 11, 2012 this is, for the lack of better words, fucking brilliant. 29-31 are jawdropping indeed! 0 Share this post Link to post

But the result sounds odd, because Doom is completely frame-based. If the engine can't push the wanted 35 FPS, the game should run slower, but should not go out-of-sync. Maybe there is some option in PrBoom turned on that allows frame skipping? Might want to play with such options. 0 Share this post Link to post
Joe Capricorn Posted April 11, 2012 How do I watch this? I tried using prBoom+ but it would go out of sync during the first level. The player would hit a corner instead of going into the room with brown and not be able to get to the exit. 0 Share this post Link to post

Might want to play with such options. Well, if screen freezes for 0.03sec it will stay on the result of course :p And the freezing is random which ends in about 1sec for every 1min desync. No matter what engine plays it :) I will try this some day http://www.doomworld.com/vb/doom-speed-demos/57958-need-help-with-making-doom-youtube-videos/ That probably works better than fraps. 0 Share this post Link to post

Use this page and a program like this one to check. 0 Share this post Link to post

miffe2000 Posted April 12, 2012 entryway said:Can you explain how you did it? I used ffmpeg to encode the video, commandline was:ffmpeg -i p1.mkv -filter 'movie=p2.mkv [p2]; movie=p3.mkv [p3]; movie=p4.mkv [p4]; [in] pad=1280:960:0:0:black [p1]; [p1][p2] overlay=640:0 [p1+p2]; [p1+p2][p3] overlay=0:480 [p1+p2+p3]; [p1+p2+p3][p4] overlay=640:480 [out]' -vcodec libx264 -an -y out.mkv Sound was split out into .wavs from the four .mkvs using ffmpeg and merged with sox and encoded with lamefor N in `seq 1 4`; ffmpeg -i p$N.mkv p$N.wav sox -m p1.wav p2.wav t1.wav sox -m p3.wav p4.wav t2.wav sox -m t1.wav t2.wav out.wav lame --preset 128 --cbr out.wav And then video and audio was muxed with ffmpeg with:ffmpeg -i out.mkv -i out.mp3 -vcodec copy -acodec copy final.mkv 0 Share this post Link to post
Looper Posted April 12, 2012 Heh, nice. Suddenly it's @ youtube. Thanks miffe2000. Could you replace the "by Paska" with "by Looper", please? I guess you should be more careful with uploading videos without authors permission? But it doesn't bother me. You did good job. The video is just how I wanted it to be. 0 Share this post Link to post

Question for entryway: Is is possible to code PrBoom+ so that the "walkcam" demo playback camera can move and turn at full speed even when watching a demo in slow motion? When I use this camera mode I usually find that it's hard to keep up with the action. Ninja edit: While we're at it, it would also nice if the "wipe screen" effect wasn't slowed down by slow motion. 0 Share this post Link to post
