Aw, perhaps someone could move this to the General Development Discussion? (Thx)

Raw Video / fullsize_buffers superfluous in mlv_rec?
April 04, 2015, 10:20:51 AM
Hello all,

I am currently trying to wrap my head around the magic lantern code, especially how the raw recording works, and I noticed that the allocated fullsize buffer in mlv_rec isn't actually used, as the edmac copy will always be done from raw_info.buffer to one of the slots. Not sure if this makes any difference, but I'd be curious if this can indeed be removed?

Thanks, and cheers for ml!

Edit: Problem solved by manually adding padding and the footer.

Hello,

I am trying to use raw2dng on a bunch of RAW file from a 5D3 1.2.3 (w/ latest snapshot). All but one file work flawlessly, but with one of them I get a This ain't a lv_rec RAW file error. The file has a size of 4,294,967,295 bytes, if this makes a difference.

Is there any chance of somehow recovering the content of this clip? (at least partially)

Thanks
Gottfried

The first 100 bytes are like this

Duplicate Questions / RAW faster than MLV on 5D3.123?
November 05, 2014, 08:34:36 PM
Dear ML community,

I hope I am posting this in the right forum / format.. the latest ML nightly for 123 works great for me, but there's one thing that keeps puzzling me: Following the tutorials out there I initially tried using the MLV_rec module to record 1080p30 continuous, which wasn't successful - first on a Komputerbay 64 GB card, then on a SanDisk Extreme Pro 64 GB card. Then I switched to the RAW_rec module instead, got what appeared a higher sustainable data rate, and finally 1080p30 working continuously with the Display option set to "hacked"! No matter which settings I tried, MLV_rec wouldn't do the same for me..

Is this the same for other users? A specific issue to the port for the 5D3.132? Or am I missing a particular knob or setting?

Happy to do any tests or the like.. from the displayed throughputs while recording 1080p30 I get about 86 MB/sec for MLV_rec (96 MB/sec with Display "hacked") and 93 MB/sec for RAW_rec (103 MB/sec with Display "hacked").

Thanks
Gottfried

Forgot to say: with "latest", I meant 1.3.3. This is also where the trace is taken from.

Hello @Baldand and all,

First: thanks for this tool, greatly appreciated!

I wanted to ask about a crash issue I am having with a 4.29 GB RAW file that I recorded with a 5D3.123, running the latest nightly from August 7. While all my other files work just fine this one crashed with the current MlRawViewer version at the time, and still with the latest (on OS X 10.9.4). Any way for me to make it work, things to try etc..?

Thanks
Gottfried
