vc++8.0 project file and some ideas

hi
i would like to ask if its possible to include a visual studio 05 projektfile for me. now i am using a mix of the old theora plugin projekt and the new source.....
and there is a question i am not able to compile the plugin with the new theoro lib, i got the some linking error like you some weeks before.. not sure is it a vc8.0 problem. well i am very interessted in this project. i need some features, that i am going to try to implement. i can imagin a windows direct x "hack" that provides you fast full screen video and i need the possibility to buffer frames before the video starts. it has to run as smooth as possible. good work man, i will to try support your work

that would be great

if you manage to do something useful, send me a patch. I have written extensive information about the plugin and how the code is organised. you should be able to dive into the code quickly.

hi
today i added some lines of code to implement something, i call it "preload".
it means the program loads the frames from the repository before the movie begins. but i dont know if this is synchronised with the sound. well its pretty funny, when the movie starts it runs petty nice, but after a short time it slows down. i dont know why it takes so much calculation time! afer that i implemented a "real" prebuffer, but it used a lot of new and delete... i think this wasnt a good idea, because allocating memory takes a lot of times. i think i will remove it, but "preload" seams to be a nice option.

definetly. precaching same 16-30 frames prior to playback.

you don't have to worry about audio right now as it doesn't work. I'll have to rewrite the audio system from scratch.

hi
After updating to the newest theora lib i got a huge speed improvement.
oh, it was note easy to built it under windows.
i implemented full screen with ogre overlay. i wasted a lot of time with directx, because its not possible to lock the backbuffer from direct3d in ogre, because the flag is not set at creation time. i went further with direct draw overlay. but this was definitly the wrong way. i made it work, but its spezific for a system and it was not realy the thing i was looking for. ogre overlay seams to be a good solution. i implemented it outside of Theora, but to keep the ratio of the video i need the dimensions of the viedo. so i added some getter functions...
---edit---
ohh forget about that... i just recognised getVideoDriver()->getHeight()
--
here is a pach...
thats what i would like to have in the new theora.
well, the prefbuf works, but not sure if this is the best solution or even usefull... take a look and let me know your opinon.
to make prebuf work with sound i also need a new pure virtual function insinde the soundsytem.
i know its deprecated, but for now its ok for me. i am yearning for the new soundsystem
