Yeah I already wrote to COBRA about this issue, it happen also if you try to open a DVD but not installing the proper plugin first, some more error-check would be good

mp4 are not currently supported, but it shouldn't hang, so I'll have to investigate. Any files to reproduce issues are welcome.

@COBRA

Great program, works fine on my sam460.
Only thing I'm really missing is an aspect correct fullscreen mode. Right now it doesn't take the monitor's dimensions into account, so 4:3 movies appear stretched in fullscreen mode on my 16:9 monitor.
The obvious workaround, resize the window to fullscreen, doesn't work since the player doesn't stretch the content beyond the original size (at least not when playing the AVIs I tried so far).
Would be awesome if you'd put that on your todo list

It sounds like PIP/Overlay does not work on your system. What gfx card do you have?

DvPlayer does scaling and aspect ratio correction in hardware by utilizing the overlay capability of the gfx card (if the gfx card has that capability and is supported by the driver). If this is not available then it will not attempt to upscale the video in software because this would lead to significant slowdowns to the playback.

Did you try with the MP4 file i sent you ?

Not yet, too busy with other things...

Radeon HD 4650 on sam460.

Actually a horizontal downscale would be okay too. Better to lose some pixels (or some frames) but get proper aspect ratio.
Could be done with a precalculated table that maps source pixel indices to destination pixel indices, table being the same for each row (or a table that maps destination pixel indices to source pixel indices by containing the offset to add to get to the next source pixel index).
Should be optional of course.

That explains, I guess there's no overlay support in the Radeon HD drivers (yet).

Horizontal downscale is not that simple, the copy routines are highly optimized and work on groups of pixels, you can't just skip a single pixel. I can only do vertical downscale which is actually done in case of DVDs where the aspect ratio is not 1:1.

However using compositing to do hardware scaling would be an option. Do the latest Radeon HD drivers support compositing?

yes, you're right there isn't overlay support in RadeonHD yet, and i advise everybody to disable overlay in DVPlayer (overlay=no) if you use it on graphic cards without overlay support in their drivers otherwise you could crash the system in some case if you try to resize dvplayer window, but the compositing is fulll enabled on RadeonHD, is possible to use it to do hardware scaling and to speed up the videos ? Without overlay my poor AMCC460 is very busy and with some videos the cpu goes to 100% and i can't watch them at full speed, thanks in advance.

I think it's possible to do scaling with compositing, BUT... as far as I know with compositing you can only have RGB bitmaps. One big advantage of overlay is that you can use directly use YUV420 mode that most video codecs output the frames in, which basically means:

1. No YUV to RGB conversion necessary (recude software overhead)
2. Only 12 bits per pixel have to be transferred to video memory (as opposed to 16 or 32 bits per pixel depending on what screen depth you use) which gives a further speed increase
3. With overlay you can do triplebuffering with vsync

These are currently not possible with compositing as far as I know.

on os4depot there's a program of Salass called CDXLplay with souce code included, it to does the scaling use CompositeTags() function from graphic.library, you could add this feature in your DVPlayer and the user could decide to use overlay or compositing to do the scaling, example through a tooltype setting, we could compare the speed difference between overlay and compositing, please consider it.
