Squeezing the last bit of performance out of MLV Lite (for testers)

[a1ex]

Result from last night (1920x1080, 30 fps, forgot global draw on at default settings):

Three problems:
- the MLV version appears slower (or maybe my script is not handling the MLVs properly; investigating)
- the random number generator doesn't seem very good (it picked MLV only two times)
- the script stopped recording for some reason after about 3 hours (I suspect overheating)

[Frank7D]

A: 32M-RAW.MO
Count = 56
Mean frames = 992

B: UNIFIED.MO
Count = 70
Mean frames = 972

C: 32M-MLV.MO
Count = 16
Mean frames = 790

A vs. B
T -Stat: 0.70
Critical T: 1.66

A vs. C
T -Stat: 4.11
Critical T: 1.70

B vs. C
T -Stat: 5.80
Critical T: 1.71

So A and B both beat C (32M-RAW.MO and UNIFIED.MO beat 32M-MLV.MO)

Partial results after some small tweaks to the script:

So, unless there's a problem with the script analyzing the MLVs (which I'll double-check shortly), it looks like something is really slowing it down. Figure out what...

[DeafEyeJedi]

Still trying to get the script to run on 5D3 but here's what I was able to accomplish from the past few nights of practice runs.

5D3, 1920x1080p, 30p global draw ON with builds from reply #42 vs the current nightly (also did 60p @ 1728x584p just for kicks).

Unified (nightly):
30p = 31s
60p = 10s

e78c7b8:
30p = 35s
60p = 11s

30bb06a:
30p = 27-28s (probably due to overheat? will test some more)
60p = 8-10s

I also noticed you added the rawbench.lua file on your recent post ... downloaded and will place it into script folder within ML and hopefully it'll run it overnight without overheating it? Ha.

*edit*

I just started to run the script on 5D3 or at least thought so but I keep getting this error saying "unexpected symbol near '<\5>' ... any idea what I could be doing wrong?

Thanks, @a1ex!

[a1ex]

To run the script, compile lua_fix and run the tests on top of that branch.

Under ML/MODULES/RAW_REC you can place binaries from other branches, so the script will pick them for testing.

[a1ex]

Another test: I've aligned the MLV header at 512 bytes.

5D3, 1920x1080, 30 fps, global draw on. 32M-MLV.MO is the one from reply #42 (30bb06a), and HDR512.MO is the one with header aligned at 512 bytes (b658401).

I've merged lua_fix, so you should be able to run the automatic tests with the next nightly.

How to use:

* highly recommended: a power adapter, so you can leave the camera overnight running the test
* set up your raw recording preferences
* review rawbench.lua (don't run code from strangers without understanding what it does)
* save rawbench.lua into ML/SCRIPTS/ on your card
* save stats.lua into ML/SCRIPTS/LIB/
* create ML/MODULES/RAW_REC and put there any raw_rec.mo files you want to test (any recent versions would work), either old raw or mlv_lite, renaming them as needed (8.3 filenames)
* mlv_rec.mo binaries might work as well (not tested)
* start the camera in movie mode and follow the instructions on the script console
* when you think it's enough, stop the camera and look at ML/LOGS/RAWBENCH.LOG



To test old versions that can't run on this code base (such as reddeercity's "gold standard" raw_rec, which doesn't run on latest core), you can use this trick:
* place the old ML build on the card
* record a few clips manually
* place the latest nightly on the card, including this script
* start the camera outside LiveView; the script will analyze the clips (count the number of frames), but it will not record anything
* check ML/LOGS/RAWBENCH.LOG
* format the card, keep ML (it will also keep the log)

As you can see, the analysis happens on camera; you don't have to run anything on the PC.



But if you don't mind processing the files on the PC, here's an alternative workflow for manual testing:
* place the old ML build on the card
* record a few clips manually
* place the card in your card reader
* run these scripts on your DCIM directory to analyze the videos (Linux/Mac; on Windows it might work with Cygwin or msys, not tested)
* copy the output from the console



You'll probably want to test the latest MLV Lite (raw_rec.mo) against the "classic" raw_rec from reply #42, and against the one from unified.

So, the questions that should be answered by testing are basically the same:

- are the speeds identical in latest MLV Lite vs latest "classic" raw_rec?
- how do they compare (speed-wise) with the raw_rec from the nightly?
- any bugs in mlv_lite that are not present in the "classic" raw_rec? (I've found one with this script, and hopefully fixed it, but... who knows)

Having mixed success with the rawbech.lua script. Feedback can be found here: https://www.dropbox.com/s/q5s1whs1vsqwph7/Rawbench_Testing.7z?dl=0

stdev too large

This is from the raw backend trying to compute the black level (it may also help diagnosing pink frames); you can ignore it for this test.

Looking at the log files generated, I can't tell which raw module was executing

This happens right after formatting the card, before restarting. I don't see it in the log file though, but I pushed a possible fix.

I also didn't see the rawbench.lua script under any menu

The menu code is commented out; the script now runs unattended.

However, assuming that it is working correctly, for this script to provide you with any meaningful feedback I think that it needs to limit the size of the size of the clips that it records. To say "2 minutes" before stopping and moving to the next iteration.

The script assumes you have picked recording settings that do not result in very long clips. But, indeed, I can see why a timeout can be useful, so I've hardcoded a 1-minute timeout.

I think that the rawbench or stats scripts are not correctly handling instances when there is just a single raw clip in the DCIM folder on the card (even if it is a multi chunk one).

True, but I don't see it as a problem, since you need many test clips to get a relevant result. I just delete those lines from the logs.

Thanks for the detailed feedback.

At the minute mark the error in the linked screenshot was displayed and the camera continued recording.

Sorry, its a bit blurry

Which raw_rec module is running?

Stopping at 1 minute should be OK now.

The other... I'm not sure where to look. Do you see the raw_rec version messages on the screen (including "For next experiment"), right after formatting the card, but before restart?

[Ottoga]

Can't look at this again for a couple of hours.  Will test it again tonight though before hitting the sack.

The 1 minute restart is working fine now thanks. I've also tried it with settings that won't record continuously and it is looping through that nicely as well.

Also, I am seeing the raw_rec version messages on screen. They don't stay for long, but they are there.

Thanks for your time and effort to get this script working for. I'll put a recharged battery in tomorrow and let it run until it dies. It should give a few cycles of good info for you.

[a1ex]

Another test worth trying is api_test.lua (it also tests file I/O, among other things). Might give some hints.

@A1ex

Here are the test results after running rawbench.lua. I ran two series of tests, one with global draw on and the other with it off. I transposed the log file details into a spreadsheet in a format that is bit more readable for me. I'm not sure if all the required log entries have been written into the log or not. As such, the original log files are supplied as well.

I also ran the api_test.lua through a couple of cycles as you suggested and have included the log file.

Test results can be found here:  https://www.dropbox.com/s/ohr3qlav4ozh810/Rawbench_Testing_7D.7z?dl=0

Let me know if you want me to try anything else.

If we're going to do much of this, would it be possible to get the data in a predictable format?
Perhaps something like a1ex provided in Reply #58, i.e.:

@Frank7D

Happy to provide the feedback in what ever the preferred format is.

I don't know what the following are/represent or how they are calculated. Do you have a sample spreadsheet that I could follow?

T -Stat: 0.97
Critical T: 1.70

The raw_rec version info has been manually captured while the script was running and added after the event as the logging is not capturing this information. I can add the path if it's important even though the script looks for them in a specific location.

[Frank7D]

Ottoga,

Here are the formulas I am using. Note that they do not show all the math since I am using some Excel functions ("DEVSQ" etc.).

Code Select Expand

Sum of the Squared Deviations
x=DEVSQ(Data Set A)+DEVSQ(Data Set B)

Pooled Sample Variance
y=x/([Count of A]-1+[Count of B]-1)

Standard Error of Difference in Means
z=SQRT(y*(1/[Count of A]+1/[Count of B]))

Our T -Stat
=([Mean of A]-[Mean of B])/z

U (used in DF calculation)
U=[Mean of B]^2/[Mean of A]^2

Degrees of Freedom
V=(1/[Count of A]+U/[Count of B])^2/(1/([Count of A]^2*([Count of A]-1))+U^2/([Count of B]^2*([Count of B]-1)))

Critical T Value @ 0.95 (95% confidence)
=TINV(0.05*2,V)


If the T -Stat is larger than the Critical T Value, then the difference in the means of the two data sets is significant.

If someone wants the spreadsheet, I can upload it.

As far as the data format, it doesn't matter much to me except that it would be nice if it were consistent.

EDIT: I should probably give the site where I got these formulas:

[Ottoga]

@Frank7D

Interesting article. Also, thanks for your analysis. I've updated my spreadsheet as well for future use.

[a1ex]

I think I know why the raw_rec version didn't appear in the log file. When formatting the card, I should have closed the log file and reopened it afterwards...

Maybe the reason it worked fine on 5D3 was... a Canon bug?!

[Ottoga]

@a1lex

I'll try it again tonight and let you know if it is now logging correctly.

btw: When the script says finish, have a little sleep.... My camera appears to go into preview mode of a clip (don't know which one).  After the sleep period the script resumes and continues as per normal. As a result though, the camera never really gets the intended break and chance to cool a little.

Here is a link to a video captured with my phone:  https://www.dropbox.com/s/880kd2t74rddk21/20160427_193655.mp4?dl=0

[a1ex]

Got it - I ran the script without mlv_play. So, when it went to preview mode on my camera, there was no activity.
