Limits be gone.

[g3gg0]

for all cameras:

http://upload.g3gg0.de/pub_files/f23cf5caa18af51a912658eac3834ce4/autoexec.bin
(removed some of my bad-ass hacks in the startup code, so it is stock init code again )

it will scan for the MovieRecorder object in memory and display the memory addresses it found in the top line.
in the second line you will see the maximum and current file size.
the file size will get patched for 16GiB limit. (0x3FFFFFFFF)

maybe it works for other models than 600D.

WARNING: Make sure you use exFAT filesystem.
Beware! Your files, your card or even your CAMERA may get damaged

(although i dont think your camera will take any damage)

How to make the EXFAT card to load ML, I can't make it bootable so far...
Ok, found maybe: http://www.zenoshrdlu.com/macboot/macboot.html

[g3gg0]

use this:
http://chdk.wikia.com/wiki/EOScard

[scrax]

use this:

I'm on mac, but solved and about to update make_bootable.sh found this also: https://groups.google.com/d/msg/ml-devel/EWHU5ukyMt4/eAIeNAt9pl4J
it should be added to the source...

in the end used  macboot, now trying it.

EDIT:
recorded a 6Gb file, i can see it till 8:27 then image freeze but video is still played (no audio recorded)

[ilguercio]

I formatted my 8GB CF card as exFAT and made it bootable with EOS card but the camera does not recognize it as properly formatted.

50D supports exfat?

[ilguercio]

50D supports exfat?

I guess not
Recording limits are not my main concern but if there is a way to get around them, why not?
Have you had any success yet?
What if you disable sound? (just a thought)

Ok, I'm going to mess with it now. Finally have some time

[Michael Zöller]

I know this is not a wishlist, but if possible, a multi-file solution that works through modifying the file pointer would probably be a better solution considering many camera do not support exFAT.

Headers are likely incorrect. Decoding freezes in most players and tools because MOV and AVI containers seem to behave poorly with files over 4gb, esp as written. The actual stream data is fine and I can scrub it in avidemux. I'm trying to figure a way to save it without causing problems. In avi mode it splits it automatically but files are unplayable. In mp4 mode I have the same problem... but the data IS there and valid.

I cannot seek or go frame by frame (after 4gb) but if I scrub with the mouse it works and I can stop on any frame. The file doesn't seem to want to work sequentially.

[Malcolm Debono]

Does the autoexec.bin above (reply 25) work with the 60D? If so, I'm willing to try it out.

He said all cameras and its the size of a unified so I assume so... .G3gg0 isn't using movie remap?

[g3gg0]

hi,

thanks for testing!
i hoped that the solution for the models with exFAT support would be just increasing the max size.
so we would have a clean solution for these cameras.
unfortunately we now face a MOV issue with 4GiB files. annoying

so the next step is to analyze the MovieRecorder object and file writing routines to find
a sane location where to add multi-file support.
this is more than just remapping file pointer to another file, since then we would end up with
the same problems as we have with exFAT now: MOV-container issues later when merging the files.

we actually have to clean up and close the file properly and then reopen the next movie file for writing.
this is more a MovRec StateObject issue.

I can't get anything to "fix" the file. I'll keep trying tho.

[3pointedit]

It's funny as I was just looking at a 5+Gb h264 .mov file the other day. Didn't have an issue playing it from memory. It was created by the compressor we have at work. So I guess 4+gb files are valid for QT.

I can't figure out how to record a longer video on a 60D. Card is formatted in exFAT and used EOScard to make it bootable. ML runs fine and I can see the text after clicking the 'Don't click me' button (before starting recording). However, I'm still getting the 'recording has been stopped automatically' error after around 13 minutes. Sound is also disabled.

how big was the file you recorded?

did the line show:
    max: 0x3FFFFFFFF cur: 0x000(counting up)
?

[Malcolm Debono]

It did. Both files are 3.98gb

Edit: tried it again. Max is increasing while curr is staying the same.

Don't know if it's relevant, but I'm using a Sandisk 16gb card.

[g3gg0]

what is "cur" saying exactly?

[Malcolm Debono]

It remains a bunch of zeros.

[g3gg0]

okay thanks, will update the demo firmware tonight,
i guess, we are just off a few bytes in the target structure.

[Malcolm Debono]

Great. thanks

[g3gg0]

sorry, didnt have time tonight. will try this night.

[Malcolm Debono]

no worries

Its not off on 600D is it? I guess I'll have to hex edit the files and see what happens at the break.
