# Media handling
|
||
|
|
|
||
|
|
Surely media should be as easy as just putting a URL into an `img` and calling it good, right?
|
||
|
|
Not quite. Matrix uses something called a Matrix Content URI (better known as MXC URI) to identify
|
||
|
|
content, which is then converted to a regular HTTPS URL on the homeserver. However, sometimes that
|
||
|
|
URL can change depending on deployment considerations.
|
||
|
|
|
||
|
|
The react-sdk features a [customisation endpoint](https://github.com/vector-im/element-web/blob/develop/docs/customisations.md)
|
||
|
|
for media handling where all conversions from MXC URI to HTTPS URL happen. This is to ensure that
|
||
|
|
those obscure deployments can route all their media to the right place.
|
||
|
|
|
||
|
|
For development, there are currently two functions available: `mediaFromMxc` and `mediaFromContent`.
|
||
|
|
The `mediaFromMxc` function should be self-explanatory. `mediaFromContent` takes an event content as
|
||
|
|
a parameter and will automatically parse out the source media and thumbnail. Both functions return
|
||
|
|
a `Media` object with a number of options on it, such as getting various common HTTPS URLs for the
|
||
|
|
media.
|
||
|
|
|
||
|
|
**It is extremely important that all media calls are put through this customisation endpoint.** So
|
||
|
|
much so it's a lint rule to avoid accidental use of the wrong functions.
