Roger's woze

VLC itself has a “capture desktop” mode though apparently it doesn’t work with sound.  It feels a tidge slower than (if you’re on Windows) using a directshow input source that also captures the desktop.

Here’s a list of the ones I’ve found that are free to download.

https://github.com/rdp/on-screen-capture-recorder-to-video-windows-free (my own, a shameless plug–it’s free and open source!)

download it from here: https://sourceforge.net/projects/screencapturer/files/

http://www.umediaserver.net/umediaserver/download.html uscreencapture, works ok.

Other options:

http://wiki.medialooks.com/Screen_Capture_DirectShow_Filter seems quick, though I haven’t looked at them too closely (note: it expires after a time trial, so after that point you can no longer use it after that time without purchasing it).

http://www.splitmedialabs.com/download pretty fast, adds a water mark to your output though unless you pay.

http://koitsu.wordpress.com/2009/09/12/how-to-install-and-use-scfh-dsf/ is said to be pretty nice.  Haven’t tried it but looks good.

VidBlaster video switcher software is rumored to have a capture device.

So far I prefer my own, the topmost one.  I even take feature requests!

Turns out that you *can* though with a few steps.

Basically you setup an “rss feed” file somewhere that points to your streaming instance of VLC.

See http://ps3mediaserver.org/forum/viewtopic.php?f=6&t=5534

You might also be able to stream to a file (like out.mpg) and have PS3MS play that file:

This bizarre little turns of events:

you stream using VLC on windows, (for me using directshow input for video and audio), and then you try and watch the stream using VLC and there is no audio.

Interestingly, if you capture the stream then play it with MPlayer, you *do* hear audio–in fact, you *only* hear audio, where VLC plays it as video only–no audio.

Anyway the fix, I believe originally hinted here: http://forums.tversity.com/viewtopic.php?f=2&t=1160

Is to transcode to mp3 instead of to AAC.  Then VLC can play it and all is well. Wow. Bizarre.

This meant “clear your VLC preferences and start again”

derived from http://stackoverflow.com/questions/4214786/directshow-source-filter-using-dekstop-window-as-source

Also http://tmhare.mvps.org/downloads.htm has some examples/samples of directshow screen capture. Except it might need some work. Within the “Filter Graph Library” demo.

odd, but

http://www.mdxinfo.com/resources/screencapture.php

may have some clues, as also

vdub is supposed to be able to do it. http://www.virtualdub.org/blog/pivot/entry.php?id=290

Here’s some code that touts itself as super fast:

http://www.mdxinfo.com/resources/screencapture.php

http://spazzarama.wordpress.com/2009/02/07/screencapture-with-direct3d/

says “if you use getRenderTargetArea…”

http://www.codeproject.com/KB/dialog/screencap.aspx?fid=23443&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=151

says “use a Video Miniport driver, Mirror Driver”

http://tmhare.mvps.org/downloads.htm

actually contains some directshow screen capture code

that “one” downloadable is actually quite fast tho…hmm…

ack initTest
ack: Program/library version mismatch
/usr/bin/ack is 1.88

meant “re-run $ sudo apt-get install ack-grep” (on ubuntu, at least…).

could not find entry point rb_str2cstr in ruby191.dll meant “you need to update your sqlite3-ruby gem version somehow”
