For those of you who'd prefer to deal with AVIs, download ffmpeg.exe and paste this into your PRBoom+ CFG file:

# Video capture encoding settings
cap_soundcommand "ffmpeg -f s16le -ar %s -ac 2 -i pipe:0 -acodec pcm_s16le temp.wav"
cap_videocommand "ffmpeg -f rawvideo -pix_fmt rgb24 -s %wx%h -r 35 -i pipe:0 -vcodec libx264 -cqp 0 -f avi temp.avi"
cap_muxcommand "ffmpeg -i temp.wav -i temp.avi -vcodec copy -acodec copy %f.avi"
cap_tempfile1 "temp.wav"
cap_tempfile2 "temp.avi"
cap_remove_tempfiles 1

Sound is standard WAV format and video is lossless x264, all in an AVI container. This configuration is useful if you plan to do any post-processing on the video.

If you'd prefer something you can just upload directly to YouTube, change '-cqp 0' to '-cqp 20' (not lossless, but makes the file size more managable).

And btw it also says in usage.txt

If you want the music with fluidsynth to sound like SDL which uses Windows' General Midi, I've converted it to a soundfont and uploaded it here
Put gm.sf2 in PrBoom+ directory and change the snd_soundfont variable in the config file to "gm.sf2"


Awesome! In time, thanks a lot! But there is something here, when I play normally with Fluidsynth music, it sounds completely like SDL/Midi, but when I'm viddumping, music sounds like the old Fluidsynth, even though everything is setup to snd_soundfont "gm.sf2". Why could this be?

Thanks Andy, I'll try this out.

The MKV thing worked for me but the problem is cutting and editing thoses files. So AVI is a much more desirable format!

By the way I uploaded a bunch of videos on youtube, including a ton of heretic, http://www.youtube.com/user/Per0xyd

(I wish we had such a video recording tool for heretic, DOSbox's 320x200 limitation is lame)

A little problem, I tried that gm.sf2 font but some parts sound off-key or something like that: http://www.youtube.com/watch?v=HmilYEsCP1M (listen after 0:19). Help?

Also I noticed that the resulting videos end a bit earlier than the demos...

Hard to tell, it just sounds like a custom midi to me.

You may want to set hudadd_demoprogressbar in your prboom-plus.cfg to 0, that'll get rid of the white bar at the bottom.

And demos done with -viddump always skip the screenwipe effect at the end of a level, that may be why your demo's slightly shorter.

Ok, try this video, should be very noticeable here, sounds just chaotic: http://www.youtube.com/watch?v=oIzX8sTy2Zk

And thanks for the tip. :)

Hi guys, well... I've been struggling with this issue since, I don't know, one year ago? And I hope somebody can help me.

I've been using Prboom-plus -viddump parameter to succesfully record some Doom videos in youtube but when I tried to record another one, video process (normally slow) goes extremely fast and no video archive is found afterwards. When I checked stdout.txt it says this:

Well, I certainly don't understand much about this. I would appreciate if somebody can help me to solve it, thank you anyway :)

First of all, was the bump necessary? Second thing; have you read usage.txt and got the files it asks for there? If you have, the way I got it to work was to put those files in the PrBoom + folder. The command I use is -timedemo demo.lmp -viddump video.mkv you need .mkv at the end of the video file or else it won't produce. The process will take a long time due to a lit of lag but you will get amazing quality. I'll be able to explain this better when I get home but hopefully that will help.

Yes, I have all required files there (mkvtoolnix, x264, oggenc2 and of course, Prboom-plus) I added .mkv at the end of video file name and it doesn't produce a video archive. I put stdout.txt cause it may give a clue or something; as I can see "TimGM6mb.sf2" is what it's failing but I have no idea about anything else.

You could try setting the game music to OPL2 and then do a viddump, that should still have music. Can't see any other errors in the log that really stand out.
