Thanks! I will try that version.

Also this card might be wacky, it's an 600x pink transcend. I'll try a different card later.

Anyone have any idea what this error could be about:



It only happens rarely, but does happen.

Since that error happened, the camera has been recording for 10 more minutes without any more errors.

I think spanning is getting close to usable now!

Wonderful Ilia3101!
Compression error. Usually includes corrupt frame/frames. I had them when recording was disturbed of sone engdrvout routine changing regs in crop rec. But root could as well be overhead or recording edge of speed I think.
Sd_uhs working?

About to try sd_uhs with a proper card!

I have uploaded some testing builds with spanning:
https://github.com/ilia3101/mlv_lite_spanning/releases/download/test-builds/magiclantern-Nightly.2020Jan23.5D3113.zip
https://github.com/ilia3101/mlv_lite_spanning/releases/download/test-builds/magiclantern-Nightly.2020Jan23.5D3123.zip

I decided to post them as it does not seem to be causing any dangerous crashes or lockups. I have only tested 5D3.113, don't know if it will be different for 123. Curious to see people's results.

My modified mlv_lite.c and mlv_lite.h code can be seen here: https://github.com/ilia3101/mlv_lite_spanning

I did have issues at one moment, but it was just a faulty lens adapter chip messing with the camera. Not from my spanning code. Pretty certain it's safe.
