Uhm, 1% can you please check
*(0x05724+0x34)
and
*(0x05724+0x38)

The first one should be a pointer and the second one a length of the data contained in the memory pointed by the first...
uhm and +0x4C should be some kind of frame number


LOL
I just realized it's the same address we investigated for the H264 encoder stuff. That memory location is definitely important

NSTUB(0xFF111928, str:lvcdevResourceGet_LVC_OUTPUT_DEVICE_T) looks like its supposed to output jpeg or .422 depending on which paths are picked.

It doesn't take any parameters? Maybe switch all the a drives to B and then try? Or turn off asserts.

I get this and camera turns off when I call it:

ASSERT: this

That's sounds like a null-pointer exception since R0 was null

Of course, you're missing something like 30 parameters :P

So how to try it properly? Also does it delete the jpegs/4.22 afterwards? Some usb functions in there too.. .how does LV data get over USB... as jpeg? Would explain the low res.

It looks like that function is actually used to send LV data over PTP to the EOS app...that makes sense

Probably have to patch out:

>JPEG Size Over(%#lx-%#lx)'

and a:\ is the USB?

Also are the LV jpeg addresses still deadbeaf when PTP is hooked up and EOS utility streaming LV?

A and B are the card drives in dual slot cameras. The code reads the active one (it's a check on R0 to decide wether it should use A vs B and JPG vs YUV)

JPEG size over => means that current JPEG was too big, reallocate a bigger chunk of RAM and try again.

This thing might be used to send data to EOS utility, but using that in LiveView doesn't seem to help, the buffer and size are still zero (60D).

That's where you find the jpeg buffer. It's only updated in standby (low-resolution modes), including 50/60p.

Next:
- how to get a FullHD JPEG?
- how to make it work on 5D3, where there's no sign of JPEG in the RAM dump?

There wasn't any jpeg in ram but I didn't check when recording. I can only dump 8MB at a time of ram when recording before buffer gets filled and this is with the lens cap on.

LVCDEV doesn't seem to be active on 600D, so I guess it's disabled (like on 5D3). The 60D was lucky.

Well there is

FF111C58:   STRING: '->lvcdevStartDev'

on 600D. So still has to be started another way.

Also: NSTUB(0xFF11189C, str:Dev\LiveViewDevState.c_lvcdevStartDev)

called_by:str:ptpCacheDataStore_ptpCacheCreateMemo

also have: NSTUB(0xFF111630, str:Dev\LiveViewDevState.c_lvcdevInit)

Maybe it lets you chose:

FF111874:   '->lvcdevInit'    FF111648
FF111888:   'lvcdevStartH264(%d)'    FF1116F4
FF111C58:   '->lvcdevStartDev'    FF1118B8
FF111C78:   '->lvcdevResourceGet(%d,%d,%d)'

Initialize then either start h264 or startdev and then do the resourceget.

Tried init then start:

LV old didn't start for some reason and it gave all of these errors.

Tried in photo mode... after that LV  is blank. Still visible on external display tho.

In 0xb40318 FA_GetJpegSizeForLV has flags 0xb402f0 --> 0x18 0xb40308 --> 0x2c
0xb4035c FA_ GetJpegBufforLV 0xb40334 --> 0x18 0xb4034c --> 0x2c
I don't know what this means? I'm working with firmware 101 still haven't updated to 102.
Dumped 0xb3f0e0 to 0xb444b8 found some new function names.

Edit: it looks like 0xb4035c -->FA_GetJpegBufForLV is some how connected to 0xb4250c -->mvrSetD_HD, I don't understand the structure links in this area.

Of course, you're missing something like 30 parameters :P

Those, I think:



Code: [Select]
lock = TwoInTwoOutJpegPath_CreateResLockEntry(ttj_struct)
TwoInTwoOutJpegPath_work_maybe(lock, ttj_struct, &output_size, job_id_maybe)
TwoInTwoOutJpegPath_DeleteResLockEntry(lock)
chunk = GetFirstChunkFromSuite_maybe(ttj_struct.off_0x88)
jpeg_address = GetMemoryAddressOfMemoryChunk(chunk)

Some fields from that big structure:

0x00: always points to 0xa0000, passed to CreateResLockEntry
0x04: always 0x1f, passed to CreateResLockEntry
0x08: engio list, enables c0f13000 and configures a few others
0x0c: 0
0x10: engio list, disables c0f13000
0x14: empty engio list?!
0x18: engio list, starts at c0f03218
0x1c: 0
0x20: 0
0x24: 0
0x28: 0
0x2c: 0
0x30: 0
0x34: 0
0x38: ffff
0x3a: image width (16 bit)
0x3c: image height (16 bit)
0x3e: some sort of counter, increases when changing video modes
0x40: 0
0x44: resource lock gets saved there
0x48: a
0x4c: 5
0x50: -1
0x54: 3
0x58: input image buffer address
0x5c: 0

0x80: assigned with 0x20000001
0x88: memory suite where the jpeg data will be written (it's pre-allocated)
fields pointing to ROM addresses seem to be engio structures, they change with video modes

That's a lot of parameters....

But lvcdev seems there, + functions to start it. Just never used in normal mode so no examples on how to get it going.

What is jukai (its some sort of food topping) and quark? Both of those have no write address in the log.
