Been doing it for months Sbright, and the wiki.
There is nothing stopping you adding things there yourself rather than asking for others to do it...

Great news!  I'm happy to hear it!  Love the Wiki Thanks!  I hadn't read it for months.

As you can see I have added bugs to Bitbucket in the past.  I wasn't aware that it was actively being read by Coutts or anyone fixing them.  I have a huge list to add shortly.  I'm glad you are updating it when a bug gets fixed!  I hope you can delete or respond to silly requests by new users.  Saving Coutts some valuable time.  Would you like some help doing that? 

I assume I cannot update the Wiki myself?  Good work keep it up!  I'm impressed.

Anyone can update the wiki/bitbucket bug list to be honest most added are duplicates so far.

Coutts is not actively fixing any bugs, no one is AFAIK at the moment. I have spoken to Alex about some and he has offered advice and areas where to look etc.

To be honest, we need the VRAM stuff sorting and as see from Coutt`s posts its what hes been working on. It doesnt require any coding skills as such, just time, and testing. So many of the features of ML require this.

VRAM is my priority too!  Making it more stable.  I will be helping Coutts when he has time to Skype me.  I hope to be more valuable with testing and adding the Vsync feature when the time is right.  More than just testing, I can try to understand what is causing the problem...

I've began to compile a new vram wiki page for the 500d with all of my confirmed findings. This will bring everything together in 1 spot.

http://magiclantern.wikia.com/wiki/500d_VRAM_Info

I'm updating it as I add stuff today. It's going to be nice to have everything in one spot.

I just understand that at
NSTUB( 0x37304, vram_info )

we have got a table with 3 records, with structure is 'struct vram_info'
struct vram_info
{
        uint8_t *               vram;           // off 0x00
        uint32_t                width;          // maybe off 0x04
        uint32_t                pitch;          // maybe off 0x08
        uint32_t                height;         // off 0x0c
        uint32_t                vram_number;    // off 0x10
};

see https://bitbucket.org/hudson/magic-lantern/src/7c9dc58abd31/vram.h
found by Trammel months ago.

so the 3 YUV buffer addresses, size and pitch should be there..

this is confirmed with 550d 1.0.9 and 0x40D07800 / 4c233800 / 4f11d800

There are many more than just 3 addresses. So far I have found 8. I have just found 2 new ones with a resolution of 1576x961 while recording in 1080p mode. There will be 2 other new ones in 720p and in 480p modes (while recording).

I wonder just how many are out there??

Killing my battery Dead!

This is the 5th time it has happened to me.  Multiple builds for T1i 500d.  I turned my camera off at night with the switch.  In the morning it's dead.  This is very annoying and will get quite expensive!  Could it be that I took out my memory card while it was off?

Anyone else experiencing this for 500d or 550d?

I've only had that once, taking the battery out and putting it back in again after using ML usually avoids this problem.

That sounds like it might work.  At night it's easier just to leave the battery out!  Put it back in the morning.  Sounds like a solution from the 1970's remember?
