Hi,

I know Hollywood can play back anim files (iff, gif).

What I'd like to see is ability to show AVI content in a Hollywood presentation.

API command should be named "LoadVideo()" and at least have "PlayVideo", "PauseVideo", "SetVideoTime", "StopVideo" etc.

I know this is a big development task Andreas, but I see support for video streaming is in the future plans of Hollywood.

For a start, I think you could look into this code http://m68k.aminet.net/package/dev/misc/CyberAVI_QT_Sr

It's code which the author has released. It's m68k AVI and QT decoder from 1999.

Kind regards, Arnljot

The problem with video playback is simply speed. Yes, I could play a video on a SAM smoothly but there's no way to do some more with it, e.g. transition effects or moving it on a layer. 600-800mhz are simply too slow for it. Needs much more powerful hardware.

Hi, Andreas

I completely Agree that most Amiga hardware (incl OS flavours) have a problem with video playback.

However it would be a great start to atleast at first only get basic playback.

The reason why I'd personally like this is because I'm working on a game and want cut scene playback. So for now I don't need any effects, so what about baby steps?

And AROS and OS4 will get more and more powerfull hardware as time goes by, also MOS with it's Mac support...

Kind regards, Arnljot

Well, it's still a hell of work because it has to be implemented on lots of different platforms... it might come someday but don't wait for it

I absolutely understand that, and it's a v4.7 or even 5.0 feature.

But meanwhile I understand that the ffmpeg code is LGPL and can be compiled into a library for m68k, OS4, AROS and MOS, and then used in applications like Hollywood http://aminet.net/package/gfx/conv/ffmp ... 21513-m68k http://ffmpeg.org/legal.html

I'll wait I'm very patient.

The decoder itself is not the problem. Raw or MJPEG AVIs decoding is pretty trivial. The problem is the playback. AV sync and stuff... probably using hardware overlay for it etc. A lot of tricky things to consider.... just ask the DVPlayer author
