5d3: Auto ISO not working with mlv raw video

Issue #2714 wontfix
Former user created an issue

Hi,

I use the latest nightly for 5d3 1.1.3 (30.03.17). I use mlv_rec with 1080p in M mode with 180° shutter fixed, aperture fixed and ISO set to auto. Exposure override is off.

Auto ISO works fine adjusting the ISO levels as long as i do not press the record button. During and after the first record the ISO values get stuck to the latest value before hitting record. Even if i stop the record it does not adjust ISO level anymore when light changes.

When I switch to photo mode and back to video mode, the ISO levels start adjusting again until I press record again (looks like something get re-initialized).

Did I get something wrong or is this a bug?
