<\/a><\/figure>\n\n\n\n\n\n\n\nThis guide is based on a Raspberry Pi 3 board and using a Pi Camera Module v2.1. The micro SD card has a new install of Raspbian Bookworm 32bit.<\/p>\n\n\n\n
Install<\/h2>\n\n\n\n
Logging in via SSH, run an update to have the latest repo\u2019s available…<\/p>\n\n\n\n
sudo apt-get update<\/code><\/pre>\n\n\n\nUsing MediaMTX with the Raspberry Pi camera module requires a couple of libraries, install or upgrade them<\/p>\n\n\n\n
sudo apt-get install libfreetype6 libcamera0<\/code><\/pre>\n\n\n\nMediaMTX can now be downloaded. Which version you use depends on Raspbian version and Pi used. For 32bit versions of Raspbian use the \u201carmv7\u201d variant, and \u201carm4\u201d for 64bit. To check which one is running…<\/p>\n\n\n\n
uname -m<\/code><\/pre>\n\n\n\n32bit versions will respond with armv71 and 64bit with arm64.<\/p>\n\n\n\n
Visit https:\/\/github.com\/bluenviron\/mediamtx\/releases<\/a> for latest versions and download links.<\/p>\n\n\n\nCopy the link and enter in the terminal with wget prefix, below example I\u2019m using a 32bit version\u2026<\/p>\n\n\n\n
wget https:\/\/github.com\/bluenviron\/mediamtx\/releases\/download\/v1.2.1\/mediamtx_v1.2.1_linux_armv7.tar.gz<\/a><\/code><\/pre>\n\n\n\nExtract the files…<\/p>\n\n\n\n
tar xzvf mediamtx_v1.2.1_linux_armv7.tar.gz<\/code><\/pre>\n\n\n\nOf the files extracted, mediamtx is the binary and mediamtx.yml contains its configuration.<\/p>\n\n\n\n
Config and Test<\/h2>\n\n\n\n
Firstly edit the yml file so it uses the Pi camera<\/p>\n\n\n\n
nano mediamtx.yml<\/code><\/pre>\n\n\n\nScroll to the bottom of the file, replace<\/strong> the following lines of code at the end of the file\u2026<\/p>\n\n\n\npaths:
# example:
# my_camera:
# source: rtsp:\/\/my_camera
# Settings under path \"all_others\" are applied to all paths that
# do not match another entry.
all_others:<\/code><\/pre>\n\n\n\nWith the following…<\/p>\n\n\n\n
paths:
cam:
source: rpiCamera
rpiCameraWidth: 1280
rpiCameraHeight: 720
rpiCameraVFlip: true
rpiCameraHFlip: true
rpiCameraBitrate: 1500000<\/code><\/pre>\n\n\n\nNotes:<\/p>\n\n\n\n
\n- YML files require the indentation.<\/li>\n\n\n\n
- cam: – this will be included in the path when accessing the stream.<\/li>\n\n\n\n
- rpiCamera\u2026 – These are extra settings that can be specified, for example the VFlip and HFlip are due the camera being mounted upside down, a full list of options are included further up in the file.<\/li>\n<\/ul>\n\n\n\n
I also took this opportunity to disable all other protocols, just leaving RTSP on. When finished editing, Ctrl O and Ctrl X to same and exit.<\/p>\n\n\n\n
To test this config, run the binary\u2026<\/p>\n\n\n\n
.\/mediamtx<\/code><\/pre>\n\n\n\nWhile running, this can be tested using VLC on another computer on the local network, open a network stream and enter the following, replacing {ip address} with the IP of the PI\u2026.<\/p>\n\n\n

<\/a><\/figure><\/div>\n\n\nAll well and the camera output appears.<\/p>\n\n\n\n
Use Ctrl C to stop the program, as we can now add it as a service.<\/p>\n\n\n\n
Add as Service<\/h2>\n\n\n\n
To allow it to start automatically and for easier control of it the program can be created as service. To start let\u2019s move the files to a safer directory\u2026<\/p>\n\n\n\n
sudo mkdir \/opt\/mediamtx
sudo cp mediamtx \/opt\/mediamtx\/
sudo cp mediamtx.yml \/opt\/mediamtx\/<\/code><\/pre>\n\n\n\nCreate a new service file for editing…<\/p>\n\n\n\n
sudo nano \/etc\/systemd\/system\/mediamtx.service<\/code><\/pre>\n\n\n\nand add the following\u2026<\/p>\n\n\n\n
[Unit]
Wants=network.target
[Service]
ExecStart=\/opt\/mediamtx\/mediamtx \/opt\/mediamtx\/mediamtx.yml
[Install]
WantedBy=multi-user.target<\/code><\/pre>\n\n\n\nCtrl O and Ctrl X to same and exit.<\/p>\n\n\n\n
As it\u2019s a new service file, need to reload systemctl…<\/p>\n\n\n\n
sudo systemctl daemon-reload<\/code><\/pre>\n\n\n\nNow can start the service and enable at the same time so it starts when the Pi starts…<\/p>\n\n\n\n
sudo systemctl enable --now mediamtx<\/code><\/pre>\n\n\n\nTo check its running, use the following<\/p>\n\n\n\n
sudo systemctl status mediamtx<\/code><\/pre>\n\n\n\nShould get the following…<\/p>\n\n\n

<\/a><\/figure><\/div>\n\n\nNow you can access the stream again via VLC, or add as a network camera to a MotionEye setup.<\/p>\n\n\n\n
Results<\/h2>\n\n\n\n
To goal of this exercise was to reduce bandwidth on the network and return to similar levels observed when using MotionEyeOS while using a Raspbian OS.<\/p>\n\n\n\n
Below are iftop comparisons while a camera stream is open and at 1280 x 720.<\/p>\n\n\n\n
Using MotionEye, with http connection to a MotionEye server:<\/p>\n\n\n

Considerations<\/h2>\n\n\n\n
While searching for a solution I tried StreamEye, a simple program written by the same developer as MotionEye. <\/p>\n\n\n\n
While a very easy program to get up and running and it offered features close to “Fast Network Camera” on MotionEyeOS, the pure MJPEG stream resulted in approx. 40Mbps bandwidth utilisation on a 720p stream.<\/p>\n","protected":false},"excerpt":{"rendered":"
For a number of years, I\u2019ve been using MotionEyeOS on my CCTV cameras, exclusively for the \u201cFast Network Camera\u201d mode that enables RTSP for low bandwidth ingress to the MotionEye (running on CentOS) while maintaining good image quality. Finding more uses for these Pi\u2019s necessitates moving to Raspbian with MotionEye as the OS version is … Continue reading “Install MediaMTX on Raspbian Bookworm”<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[212,4],"tags":[180,376,374,375,63,378,377],"class_list":["post-915","post","type-post","status-publish","format-standard","hentry","category-network","category-raspberry-pi","tag-camera","tag-convert","tag-mediamtx","tag-motioneyeos","tag-raspberry-pi","tag-raspbian","tag-rtsp-simple-server"],"_links":{"self":[{"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/posts\/915","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/comments?post=915"}],"version-history":[{"count":4,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/posts\/915\/revisions"}],"predecessor-version":[{"id":925,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/posts\/915\/revisions\/925"}],"wp:attachment":[{"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/media?parent=915"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/categories?post=915"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/james-batchelor.com\/index.php\/wp-json\/wp\/v2\/tags?post=915"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
