Re: MMAL Motion - tuning & optimisations

Mon Aug 18, 2014 7:18 pm

These optimizations really sound great :D
And it also seems to work - to some extend.

I would like to switch off the screen after 2min of inactivity and to switch it back on when there is motion in front of it. The first part is easy: call tvservice -o after 2 minutes.
The second part should call tvservice -p if the screen is off and motion was detected. This should be done via a shell script that is called by the on_motion_detected event of motion.
Furthermore, a (single) image should be saved when motion is detected.

All this seems to work if the screen is permanently on. However, after experimenting with motion and the screen settings, it seems as if motion is not working at all when the screen is off! Log says:

The screen is attached via HDMI. Can anyone confirm this behavior?

Would it be possible to use the 2x2 binning modes with MMAL Motion with the new parameter MMAL_PARAMETER_CAMERA_CUSTOM_SENSOR_CONFIG ?

In theory, not a lot of work to add - but would require some careful testing.

I'll add it to the TODO list for when it's available in the firmware.

Firmware is already out with commit https://github.com/Hexxeh/rpi-firmware/ ... 55035adf85

The likelihood is that you're already running the binned modes as they will be automatically selected if you're asking for 30fps - I wouldn't fret about getting that in as a new feature.

Is it possible to use this as a 24/7 recording software and to disable the motion tracking? I want an old-school style CCTV system where it's always recording and I can also get a live preview through a webpage.

The refresh rate on the webpage is fairly slow but could this be improved by writing the images to /dev/shm/ as RaspiMJPEG does?

Thanks for your help,
Kev

Hi,

Just downloaded the latest version this morning and the high red images are lovely.

I've set mine up to 2560x1920 using the upscale of 5.

Images are working well using secondary, but video isn't, I've switched video output on and enabled secondary but I'm only getting the low resolution images from the primary.

Have I missed something here?

--UPDATE, FOUND THAT I HAD 2ND BUFFER QUALITY SET TO 50 - DROPPED IT DOWN TO 0 AND I'M FINE WITH 4FPS

Thanks

Simon

I'm running motion-mmal with a resolution of 1152*864 pixels and a framerate of 2 Hz. Is the 2*2 binning only available for the high framerates or can it be enabled also for lower framerates?

Following the instructions in https://github.com/dozencrows/motion/bl ... UILD-HOWTO I did this:

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade

sudo apt-get install libjpeg62 libjpeg62-dev libavformat53 libavformat-dev libavcodec53 libavcodec-dev libavutil51 libavutil-dev libc6-dev zlib1g-dev libmysqlclient18 libmysqlclient-dev libpq5 libpq-dev

cd /home/pi
git clone https://github.com/raspberrypi/userland.git
git clone https://github.com/dozencrows/motion.git --branch mmal-test --single-branch
cd motion
USERLANDPATH=/home/pi/userland cmake .
make
sudo cp configs/motion-mmalcam.conf /etc/motion.conf
./motion
and can confirm that it works. Just playing with my motion.conf now.

By the way, is there any hope of getting access to the new MMAL features, for example text annotation, or time of day? Although I suppose you'd have to mask off that part of the image from 'motion' so it wouldn't detect the constantly changing time-of-day readout as actual motion. Unless you could get the time/date selectively shown only in the scaled-up JPEG, and not the low-res JPEG that is processed by motion.

...also, as I understand it the current video output option from MMAL-Motion is MJPEG only. Is it possible to get H264 format output via MMAL (GPU, not ARM) for better storage efficiency than MJPEG?

Re: MMAL Motion - tuning & optimisations

Mon Oct 13, 2014 9:35 am

hello dozencrows,

Outstanding work.

getting back to the original thoughts around reducing image processing (motion detection) load, are there optimisation avenues to explore around scaling back the frame comparison 'rate' once motion has been detected i.e. once motion is detected only compare frame x against frame x + N where N is number of frames according to fps and a user defined period used?

I am making this suggestion without any idea around how the software glues together, but it seems logical that it could offer some additional processing capacity to increase fps for recording movie?

Apologies in advance if its stupid idea from someone with very limited programming background.

Regards
PP

Interesting idea - many thanks, pippip!

With a bit more memory use for temporarily holding onto frames x to x + 2N, there would be the opportunity to balance the motion detection load between frame x and frame x + N during the period x + N to x + 2N. Then if motion was detected, that would trigger a save of frames x to x + N, and the whole process would step on to frames x + N to x + 2N, and so on.

The benefits would be to allow higher frame rates for the recorded video, and motion detection on higher resolution source images as the effort would be amortised over time, rather than attempted in a single iteration of the app's main loop (i.e. a single 'frame').

I think there would be some challenges and limitations:
* This is effectively reducing the 'sample rate' at which motion is detected - so objects moving at high speeds might not trigger motion detection (e.g. if only captured on some frames between x and x + N, but not in x or x + N). How exactly this pans out would depend upon the image capture frame rate and the value of N.
* Encoding/saving of N frames would also need to be carefully load balanced to avoid causing stalls. Motion-mmal can suffer from this already (depending on the storage method), but I think this could make it worse without some effort to address it. The end result would be a more balanced system, performance-wise.

Would that my day job wasn't so demanding right now... this would be fun to at least try!

Oh, and there would be greater latency between motion happening and detection of that motion, of N frames.

If you want ffmpeg_output_secondary_movies to be on, I don't think you can have mmalcam_secondary_buffer_jpeg set to anything other than zero.

mmalcam_secondary_buffer_jpeg causes the Pi's GPU to encode the secondary buffer as a JPEG image before it reaches the motion code; this will not be understood by motion's movie encoding of the secondary buffer and might cause the problem you're seeing.

Try again with 'mmalcam_secondary_buffer_jpeg 0' and see if that helps.

However I think you'll get a very low frame rate, as by far the biggest load on the Pi CPU is motion's movie encoding. As motion is predominantly a cross-platform piece of software, it doesn't take advantage of any hardware to assist with the encoding.

OK Thanks. Low fps it is, unless I can find a way to later stitch jpg files into a movie and instead use jpeg output from motion-mmal-test.

The result I'm after is movie files; not fussed about streaming, so I guess this must be it to produce a .avi file -

Thank you a lot, Dozencrows, I will start with the config below and iterate it to something that works for me to output jpegs.

Dozencrows, just to be really clear - is the camera image captured at width 320 height 180 and the secondary buffer just upscaled from it by the GPU, or is the secondary image actually a full-res original image ?

Re: MMAL Motion - tuning & optimisations

Sun Dec 14, 2014 12:07 pm

I've updated the link in the github README - my apologies, meant to do that ages ago. I don't have control over other links, so inevitably some of the tutorials referencing my work are going to age.

Regarding how the secondary buffer works - it isn't in fact upscaling the image. My choice of parameter names is a bit misleading in that respect. What my MMAL code does is take the resolution values for the primary buffer, multiply them by the upscale factor, then configure the camera to capture at that higher resolution.

It sets up a stage in the GPU image processing to make a copy of the image downscaled back to the primary buffer size settings, which is used by the motion detection algorithm. The original higher resolution image is passed on to motion's output code if motion is detected.

The end result is that the Pi has less work to do detecting motion in a lower res image, so can produce a higher frame rate with higher quality output.

Also note that with the latest version of the binary on DropBox, you need to ensure the width and height you set are multiples of 16. In the example config file you quote, the height is 180 which is not a multiple of 16 - try 192 instead.

Also make sure you have up-to-date Raspbian and firmware; there have been problems in the past with suspected camera firmware bugs (e.g. http://www.raspberrypi.org/forums/viewt ... 00#p571300).

Haven't you solved this "bug" recently by falling back to the number that is nearest to mod 16?

Yes, but I haven't updated the Dropbox binary with that fix :oops: ;)

Re: MMAL Motion - tuning & optimisations

Just read through this thread and I was wondering if there was ever a fix released to be able to rotate the video 180 degrees, I saw the suggestion of using -vflip, but that doesn't seem to affect my images :(

Edit: Nevermind, I just realized that I needed a second dash for it to flip things correctly. I.e.

Code: Select all

--vflip
instead of

Code: Select all

-vflip
Dear forum: Play nice ;-)

OK. As at 2014.12.15 ... for absolute beginners like me, here's the .sh file I used to build the latest version of motion-mmal-test from the GIThub source, on the Pi. In the following post is a working motion.conf file which you can tailor your needs and save as /etc/motion.conf (it saves jpg files, not a video, using secondary buffers for lower cpu usage).

(beginner "Windows users": careful when editing text files on Windows and putting them back onto the Pi, Lunix it doesn't like windows text file formatting, so review the example SED command in the top of the .sh file for an example of how to fix that on the Pi).

Code: Select all

#!/bin/bash
# also fix scripts, turning them from MS-DOS format to unix format
# to get rid of MSDOS format do this to this file: sudo sed -i s/\\r//g ./filename
# or, open in nano, control-o and then then alt-M a few times to toggle msdos format off and then save
# make the file executable by doing the following:
echo "Turn bash scripts from MS-DOS format to unix format ..."

The reason I use .JPG output instead of movie output is that "using the secondary buffer" prevents capture timestamps being imprinted on both video or JPG - hence I
1. capture to jpg and rely on the filenames for the timestamps
2. copy the jpgs to a Windows PC
3. run a batch script to imprint the timestamps and turn them into a .mp4 movie (using ffmpeg)
