# streamupload
|
||||
**Upload videos to be re-encoded and scheduled for streaming**
|
||||
|
||||
## Install
|
||||
* Prepare a server, set its timezone to the users' timezone
|
||||
(on deb-based systems: `dpkg-reconfigure tzdata`)
|
||||
* On the server, `cd` to the place where you want the files
|
||||
* Clone repo: `git clone https://gitlab.com/pepa65/streamupload`
|
||||
* `cd streamupload`
|
||||
* Change the value of the `repopath` variable in `stream` and `encode`
|
||||
to the output of `echo $PWD`
|
||||
* Run a php/webserver on $PWD/uploadpage
|
||||
- Get it to restart on reboot
|
||||
- Setting up basicauth on the page is a good idea if others can get access!
|
||||
- Change the relevant `php.ini` to allow large file uploads:
|
||||
* `post_max_size` - Upper limit of uploaded video sizes, say `10G`
|
||||
* `upload_max_filesize` - same value as `post_max_size`
|
||||
* Make a crontab-entry: "* * * * * $PWD/encode" (replace $PWD with its value!)
|
||||
|
||||
## Usage
|
||||
* Get a streamkey for the target by scheduling a stream
|
||||
(supported are: Restream.io, YouTube.com, Facebook.com)
|
||||
* Go to the server's IP address in the browser: `http://$ipaddress`
|
||||
* Fill in the form, click "Schedule Stream"
