Recording video within DOSbox, not supported?
 

So I went into the DOSbox readme after hearing that it can record video (i've got v .72), and sure enough, in the help file, it says ctrl+alt+F5 will record a movie and sound of the game.

So I go into my games and try it; every time, it comes up with nothing but an audio file in .avi format.

I've ran it through MPlayer, through VLC player, through Adobe After Effects, through Virtual Dub, and a ton of other things, and every time, it comes up saying "cannot read video" and it only reads audio; i've got a TON of codec packs on my computer too, so it's not like i'd be missing basic codecs...

Anyone know why it's only recording audio or of any way to fix this?

Oh yes it works.

You say you have a TON of codecs, but do you have the right one?
Also: it is possible that the frontend blocks the videocap.
Learn running dosbox from the prompt.

As you can read -(nice thing those readme)- you need a correct C mount and the 'zmbv' codec.

I doubt if it will work with frontends. As I never use frontends I can't help you further.

Install the ZMBV video codec included with your DOSBox installation and the videos will play correctly. You can then use something like VirtualDub to re-encode them to a different format, if you want.

Yup, that worked fine.

What puzzled me is that it didn't even work in MPlayer; usually ANYTHING that won't work in WMV or VLC or anything else will work in Mplayer, and if it doesn't, it crashes;

However, this time it actually said "no video detected" and just played the audio on the clip until I installed the new codec that you were talking about; weird stuff.

i think that the zmbv codec is present in ffmpeg which provides most codecs to mplayer.

unless it's some recent version, i got the ffmpeg pack a year ago and still have it, but it didn't have it in there

a year is a long time in codec land
I don't know when it was included though.

What programs do you use to replay the .avi-files?

I tried Irfan View but it always quits with an error message.
If you know a good, simple and reliable one please let me know.

(and YES, I did properly install the codec that came with dosbox 0.72)

Media Player Classic.

For AVI, you can use VLC, which is free and fairly uncomplicated. I use that to watch AVI movies and it works like a charm. You'll still need codecs though. No way around that as far as I know. If you don't have the codec it doesn't matter what player you use.

There are some codec packs out there with busloads of codecs in one.
