With the latest build and MLV_SND, when I record Global Draw goes off and I can't re-enable it without rebooting.  The option in the MLV module is OFF too.

Any idea?

Sort of counterintuitive, but it worked!  Thanks.

Been doing many tests and now I only get the MLV files recorded to the card. The sound is still working great, but the IDX files are no longer being created. Anyone know what could be the reason? I tried formatting my cards an reinstalling ML files and that didn't change it. I don't have a use for the IDX files at the moment so I am not complaining, just curious. :)

I am having so much fun with this sound recording development. Its like the best Xmas gift ever! Thanks again g3gg0 and the ML team!

can you upload such .wav?

Sure. Here it is:

wav straight from mlv_dump
https://www.dropbox.com/s/mst85gtpzutwd7o/m24-0223_frame_straight%20from%20mlv_dump.wav

the same wav from goldwave - playback changed from 44,1 to 48khz  - seems quite correct.

Hello g3gg0,

I downloading the recent nightly build of MLV Raw, but before I could get a chance to test the audio I ran into an error.

After recording a video in MLV it will always state "stopping..." and unless i shut off the camera and turn it back on, it will always state "stopping..."

Thanks g3gg0, this is invaluable. And thank you also for advancing the whole file format stuff in the first place.

Haven't tried the new build, but already the first build worked great on 5Dm3. Sadly I am still plagued by random crashes and not shutting down until pulling the battery when using an external monitor. But this also happens with the traditional raw_rec.mo

Hi G3gg0,

If it won't take too much of your time, is it possible to put in some more horizontal video resolution options in the MLV module?
In some raw.rec builds there where options for 1792 pixels wide and 1664 pixels wide resolution.
The 1792 resolution is probably only used for 6d owners, but I happen to have a 6d and love the 1792 pixel wide clips. 

Further, THANKS for the audio recording in combination with raw video!
Works on my 6d (using the tragic lantern build of 30 November), audio clips are a little bit longer than video, but it seems in sync, it only records some more audio after video recording has stopped.

How to monitor level with this?Can anybody help?I will post a workflow tutorial for Final Cut Pro.
It goes like this >mlv dump>convert dng's to Visionlog>compressor 4.1 to export Prores 4444 with audio>Final cut pro with LUT utility for grading.

Very good quality to my eyes

update:
 - added mlv_snd which adds audio recording to mlv_rec

Great work g3gg0!  I just tested this and it worked very well... I had perfect sync when post-processed.  I only recorded 25 seconds so I'll try to record something much longer to test that sync is maintained for an extended period.

OSX Users:

i recently installed a OSX machine inside a virtual box.
after some struggle regarding installation of the necessary stuff i was able to compile mlv_dump in the VM.

can you try this mlv_dump?

update:
if you use OSX 10.6 or 10.7 does the link above work?
if not, can you try this mlv_dump?

I've tried this in terminal on both 10.7 and 10.9 on both I am getting a response of "command not found".  Am I putting in the correct command?  I'm not much of a terminal user...

BINGO!  I read a little more and realized my mistake. chmod +x ./mlv_dump.osx needs to be executed first.  Second one works well in 10.7.  First one says 'illegal instruction 4'

Thanks.

this actually makes the process seem far more complex than just converting dngs in Resolve...

AnotherDave,

Do you know of a way to link up the audio in Resolve automatically based on filename? I can align the audio manually in the timeline, but I wonder if there is a way to align the audio for the clips automatically by name.
