Those of you who had problems with recording, which audio card / driver you are using?

I'm using HD Audio and noticed that I have to choose 16-bit recording from HDMixer, otherwise DoIO() gets stuck. Not sure how to deal with this on SDL side when using the AHI device API.

@jabirulo

Your example is ignoring the return value of SDL_GetWMInfo function and it has a superfluous cast to struct Window *.

Maybe some issue in SDL2 audio capture code. Testaudiocapture binary doesn't seem to work properly anymore either.

No, it shouldn't have code like that.

@trixie

It's possible to get window pointer but it's not protected in any way.

SDL2 doesn't use window.class.

What kind of functionality you are looking for?

@smarkusg

Did you ever try to force XRick to use SDL_SWSURFACE (bitmaps in RAM) instead of SDL_HWSURFACE (bitmaps in VRAM)? Does it change anything?

@Raziel

FYI, Sam fixed the window surface issue: https://github.com/libsdl-org/SDL/issues/8011

@smarkusg

I'm worried about a potential issue if application requests 32-bit bitmap but gets 16-bit. If application doesn't check what it gets, then it will crash probably or at least render incorrectly. EDIT: I forgot SDL actually allocates a shadow surface so application should get bpp it wanted.

Maybe we can write a small example which tries to render in 32 8-bit (like XRick), and test that on QEMU and others?

EDIT: fixed some issues in original response.

@Maijestro

SDL has a possibility to grab mouse inside some window so grabbing may be intended from application's side. I hope there was a smaller example than MPlayer to check. But if you can point me to the relevant version of its source code, I can try to take a look.

@Maijestro

We probably don't have CSound, SuperCollider etc. Maybe they are not mandatory.

MilkyTracker itself is quite simple to build using a cross-compiler and cmake, or even natively if you get cmake working.

@Maijestro

These fixes were done some time ago, but if I remember correctly:

testviewport was visually wrong, drawing was in wrong place with compositing.

Some cases of testautomation failed with compositing, because bitmaps were not initially filled with 0, like software surfaces. So behaviour is now consistent.

2.28.4 RC1 is available:

AmigaOS 4 specific changes:

@rjd324

Just to add that SDL2 is a dev branch (SDL 2.29) and there are separate release branches so you probably want to use 2.28 branch. This is similar to upstream.

Ideally repo name would be just SDL like in upstream but there is an obsolete repository with the same name already under AmigaPorts, based on the unofficial mirror from times when upstream used their own Mercurial repo.

@trixie

I got your e-mail, sorry I forgot to reply. Anyway, I wanted to work on the port first before giving any promises :)

There is a new version available: https://github.com/capehill/MilkyTrack ... es/tag/v1.04-rc1-amigaos4

@smarkusg

So you are testing E-UAE? Is that built using newlib or clib2? Can you do readelf -d on binary?

And which C library sdl12-compat is using?

Maybe you could install debug variant of the SDL2 shared object over normal .so and use sashimi to collect serial logs. Actually, it should work even if you make a local SOBJS directory in application dir and copy debug shared object there with a proper name (no _debug).

@smarkusg

Zoom level 4 works? How about zoom level 1 and 3 (2 is default)?

@Maijestro

So, XRick is using 8bpp in HWSURFACE mode. For some reason this doesn't work on Pegasos(QEMU) in 16-bit mode (?). And possibly window size can have some impact? (for example zoom option in XRick)

Can somebody test XRick on a real Pegasos in 16-bit mode? If somebody already did, then sorry, I have missed that information.
