[Prboom-users] PrBoom newbie questions: Selecting an ingame demo and fast video playbacks.

[Ant <an...@zi...>]

Hello.

I am trying to record my old DOOM 2 v1.9 mods.  
(http://zimage.com/~ant/antfarm/files/doom2/j2doom/j2doom.html )'s in 
game demos. I am having two issues:

1. How do I select the specific ingame demo in my WAD?

2. After doing two quick test records, my video demo playbacks are 
showing gameplays too fast in both Media Player Classic-Home Cinema and 
VideoLAN Client players. How do I fix this? :(

Thank you in advance. :)

I think it was by using "-playdemo demoX" where X is one of 1, 2 or 3 from the commandline.

Are you using PrBoom+? Because PrBoom doesn't have a way to record actual Video. You might have more luck asking on the doomworld forums.

Perfect: E:\dl\doom\prboom-plus-2.5.1.3-win32\prboom-plus-2.5.1.3\glboom-plus.exe 
-playdemo demo3

Yes, but huh? Win32 prboom-plus-2.5.1.3\usage.txt says this which is 
what I am doing:

"VIDEO CAPTURE

This feature allows you to record movie files, suitable for viewing or 
upload to websites.
Prboom-plus uses external command line encoding tools to accomplish 
this.  You will need the following:
  oggenc2            ;ogg vorbis audio encoder 
http://www.rarewares.org/ogg-oggenc.php
  x264                      ;h264 video encoder             
http://x264.nl/
  mkvmerge            ;mkv muxer 
http://www.bunkus.org/videotools/mkvtoolnix/

These applications can be placed in the same folder as Prboom-plus..."

Using the movie recording feature is simple.  The command line parameter 
is "-viddump filename", and is meant to be used with -timedemo.
Example:
  prboom-plus -timedemo 30uv1437 -viddump foo.mkv
  
This will create foo.mkv playing demo 30uv1437.lmp.  By default, foo.mkv 
will be an mkv container containing h264 video and vorbis audio, which 
most popular video sharing sites should understand.

The recording uses all of your normal video and sound options, so make 
sure things like video resolution, gamma correction, audio samplerate, 
and sound volume are how you want them beforehand.  Both OpenGL and 
software renderers are supported.  Music recording will happen as long 
as you are not using the SDL or Portmidi music options.  The video and 
sound are encoded as the demo is played, so the process can be slow even 
on a fast computer.  But, regardless of how fast the encoding goes, the 
resulting file can playback at full speed with perfect sound sync and no 
dropped frames.  Note that while you can watch the demo as it records, 
you will not be able to hear any sound..."
