ZoneMinder Forums

I have been trying to max out this RPI3. I have found out that I was probably already using libturbojpeg. I was able to build a libturbojpeg 1.5.1 package and it resulted in the following debs: ii libjpeg-dev 1:1.5.1-12 all Development files for the JPEG library [dummy package] ii libjpeg-turbo-prog...

Was able to compile the latest source from 5-12-17 with neon optimizations. I added the h264_mmal line as well. I redid the cpu testing for the original unmodified zoneminder and ffmpeg from the repo using pidstat cause the numbers were jumping around a bit for the neon optimized version. I think al...

I'm really new to this. What is the procedure to download the source from git with the neon optimizations? I have just been downloading the latest source and then downloading each modifed file. I was able to build a package again, just incorporating the latest change to zm_image.cpp. I will run it f...

I realized the latest source did not have the neon optimizations. I downloaded the modified files and was able to successfully build a package. However, it does not run. I am getting these errors in the log: zmc_m4[16777]: PNC [Delta grayscale function failed self-test: Results differ from the expec...

Well, after running for 6 hours, I got the following from top: 1886 www-data 20 0 187460 47604 44112 R 25.5 5.4 0:18.84 zma 1857 www-data 20 0 187444 47516 44032 S 22.5 5.4 0:16.59 zma 1879 www-data 20 0 225708 56512 48636 S 11.6 6.4 0:09.41 zmc 1850 www-data 20 0 225824 56696 48620 S 11.3 6.4 0:09....

Compiled the latest source with neon optimizations. zmc' with further reduced cpu utilization and also zma. By the way, this is with sv3c cameras using rtsp feed of 640x360.

I added the fallback to h264 software decoding if h264_mmal is busy. I got the following results with top: With software decoding only for 2 cameras: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 32339 www-data 20 0 186412 47100 43688 S 25.2 5.3 0:56.73 zma 32291 www-data 20 0 189772 53600 4...

Seems to be working. It cut zmc's cpu utilization by 50%. My test system is single camera with h264 so dont have to worry about competing zmc processes for one pipeline. I am running raspbian with the following specs: pi@raspberrypi:/mnt/DISK1/build/zm/mmal $ dpkg -l | grep ffmpeg ii ffmpeg 7:3.2.4-...

Is there any benefit to using h264_mmal ( the hardware accelerated codec for H264 decoding in the RPI ). The latest ffmpeg libavcodec has support for this codec along with h264_omx (h264 hardware encoder codec). There is only one pipeline though, so only one of the zmc processes could use the codec ...
