Title: Card spanning ON, but SD remains idle in all configuration 5D3 built 08-02-2014
Post by: tjaja on February 09, 2014, 12:30:04 AM
Hello folks,

when using the MLV_rec module the card spanning option doesn't work anymore(did so a month ago)
From 1080p30 and up it's quite useful.

Tried the following:
Format the two cards to exfat
Format the two cards to fat32
Turn off CF only buffer, and cf only 1 etc
Tried the 4 buffer methods and off
-Varied record func+card/folder sel. from the Canon menu

When benchmarking CF+SD write from the debug Magiclantern menu both cards are working.
When putting mlv_rec on test mode it doesnt work( gives a avarage from the 2 cards, and with sd being idle it lower than cf only)

Anyone got a clue?

What camera?

Any idea when it broke?  Download some older nightly builds to check.
It's working here on a build from about a week ago.

On the 5D3,

Sorry, I should wake up better before answering questions.

In that case, it's not something that broke in the code.  Are you sure you're pushing the limits hard enough to make it use the second card?

Im trying to push it to the second card use: 1080P 30fps
with frame skipping allowed it doesnt use the second card, with skipping off it stops.

Here is another weird thing: When I use SD as preferred card from the card settings
recording to the sd goes perfectly but CF is idling. with 20mb/s
It is as if card spanning isnt allowed or something.

If someone is experiencing the same thing I would also like to know. Clearly the card is not corrupted and I tried all the settings.

Nothing broken I guess: even though it says card idling its not.
On display while recording: Totalrate 45MB/s
A:/ 70MB - 90MB
B:/ idle

on 1080p30 with frame skipping enabled it is saving to the sd card. Test mlv of 14.8GB:
12 GB to CF
2.8 GB to SD


On build 11-2-2014 configuration: Memory hack ON/ Extra Hack OFF/buffer fill method 4/ CF-only buffers 0 /card spanning ON

formatted exFAT
LEXAR 1000X 32GB CF and Sandisk Extreme 45MB/s 32GB
