CustomMedia

A fork of Plan9's CustomMedia project that adds a whitelist-based version for choosing specific homeservers to pull media from directly. Conserve your matrix homeserver's precious storage space and bandwidth with this one simple webserver.

Requirements

• Python 3
• gunicorn - pip3 install gunicorn

Nginx configuration

Add this inside of the block that matches for requests to /_matrix, replacing server\.org with your own homeserver

location ~ ^/_matrix/media/(?<folder>[^/]+)/((download|thumbnail)/(?!(server\.org)/))(?<file>.*)$ {
proxy_pass http://localhost:9999;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_read_timeout 3600s;
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';
}

systemd Service

Clone this repository into /opt, check that custommedia.py has permission to execute, then use this systemd service (replacing custommedia.py with one of the other ones if desired):

[Unit]
Description=Custom media
After=network.target
StartLimitIntervalSec=0

[Service]
Type=simple
Restart=always
RestartSec=5
User=root
WorkingDirectory=/opt/CustomMedia
ExecStart=/opt/CustomMedia/custommedia.py

[Install]
WantedBy=multi-user.target

Mappings

CustomMedia uses a mappings.json file to cache which domain a homeserver's media is on (unless using the -morg.py version). This file will automatically be created in the working directory if one does not exist, but one has been provided here with some common homeservers.
