Hi,

I would like to write video (created from series of bitmaps) to some popular video formats like avi, flv. Is this possible? Has FPC bindings for video librarys?
I googled that WinFF (http://winff.org/html_new/) is written in FPC and Lazarus, so I supose that some bindings exists but can't find any in http://wiki.freepascal.org/Multimedia_Programming

Regards.

In my opinion, the easiest way is to create a series of BMP's and then use VirtualDub or VirtualDubMod (I think it's at Sourceforge).

Greetings

Hmm, external application is nice idea. But VirtualDub is windows only. Anyone know multi-platform comandline video converter? What I found is Mencoder. I must test it

Apart from _the_ multi-platform commandline video converter, ffmpeg? http://ffmpeg.org/
It's the back-end for WinFF (and most other utilities like these). Also, I would expect VirtualDub to run fine with WINE.

Ffmpeg looks similar like Mencoder project. So I have some solutions for output encoding, but there is a problem how to send frames to this encoders. Mencoder can encode video from series of PNG files, but can't find similar option in ffmpeg. Anyone know something about RAW video format? It seems that this is some standard and most of players / encoders can handle it. I could use it as input for ffmpeg/mencoder but need some bindings / tips for FPC

That's the command line to convert a png file image to a mpeg2 video format, using ffmpeg:|
||
|ffmpeg -f image2 -vcodec png -i menu.png -target pal-dvd -vcodec mpeg2video -an menu.mpeg|
||
|this makes me believe that the ffmpeg libraries should provide all what's required.|

VirtualDub(Mod) accepts as input a series of BMP
(name000.bmp,name001.bmp,name002.bmp,...)

You can give it a script file for execution. The best is to do it by hand once and save the script, then you know what your program must generate.

ffmpeg can read a stream of frames directly from stdin. I don't have a working exmple now but I once used this to pipe a stream of ppm images from another application to ffmpeg.
