## My browser plays the video. How do I download it?
2016-10-05 15:08:46 +00:00
2017-12-20 10:21:36 +00:00
Most recent browsers automatically play a video
if it is a format they know how to play.
2016-07-27 11:20:13 +00:00
You can ususally download the video by doing *File > Save to* or *ctrl + S*.

## Why is [alltubedownload.net](https://alltubedownload.net) so slow?
[alltubedownload.net](https://alltubedownload.net) is hosted on a free [Heroku server](https://www.heroku.com/pricing)
so it has low RAM and CPU.
AllTube probably won't switch to a more expensive hosting
because this project does not earn any financial ressources
(although [donations are welcome](https://liberapay.com/Rudloff/))
and you are encouraged to host it yourself.
## alltubedownload.net often says "An error occurred in the application…"
See above.

## How do I change config parameters?
2016-10-05 15:08:46 +00:00
2017-05-15 05:25:14 +00:00
You need to create a YAML file called `config.yml` in the `config/` folder.
2016-10-05 15:08:46 +00:00
See [`config.example.yml`](../config/config.example.yml)
for a list of parameters you can set and their default value.

## How do I enable audio conversion?
2016-10-05 15:08:46 +00:00
2016-07-27 11:36:31 +00:00
In order to enable audio conversion, you need to add this to your `config.yml` file:
2016-10-05 15:08:46 +00:00
2016-07-27 11:36:31 +00:00
```yaml
convert: true
2016-07-28 00:07:40 +00:00
avconv: path/to/avconv
2016-07-27 11:36:31 +00:00
```
2016-10-05 15:08:46 +00:00
You will also need to install `avconv` on your server:
2016-10-05 15:08:46 +00:00
2016-07-27 11:36:31 +00:00
```bash
sudo apt-get install libav-tools
2016-07-27 11:36:31 +00:00
```

## How do I deploy AllTube on Heroku?
2016-10-05 15:16:28 +00:00
Create a dyno with the following buildpacks:
* `heroku/php`
2017-01-01 18:32:19 +00:00
* `heroku/nodejs`
* `heroku/python`
You might also need to add the following config variables:
```env
CONVERT=1
PYTHON=/app/.heroku/python/bin/python
```
2016-10-05 15:16:28 +00:00
Then push the code to Heroku and it should work out of the box.
## Why can't I download videos from some websites (e.g. Dailymotion)
2017-12-20 10:21:36 +00:00
Some websites generate an unique video URL for each IP address.
When using AllTube, the URL is generated for our server's IP address
2017-12-20 10:21:36 +00:00
and your computer is not allowed to use it.
There are two known workarounds:
* You can run AllTube locally on your computer.
2017-01-19 21:29:34 +00:00
* You can enable streaming videos through the server (see below).
2017-12-20 10:21:36 +00:00
Please note that this can use a lot of resources on the server
(which is why we won't enable it on alltubedownload.net).
## CSS and JavaScript files are missing
You probably don't have the minified files (in the `dist` folder).
You need to either:
* Use a [release package](https://github.com/Rudloff/alltube/releases)
2017-10-17 13:27:57 +00:00
* Run `yarn install` (see detailed instructions in the [README](../README.md#from-git))
2017-01-11 11:29:31 +00:00
## I get a 404 error on every page except the index
This is probably because your server does not have [mod_rewrite](https://httpd.apache.org/docs/current/mod/mod_rewrite.html)
or [AllowOverride](https://httpd.apache.org/docs/current/mod/core.html#allowoverride)
is disabled.
2017-01-11 11:29:31 +00:00
You can work around this by adding this to your `config.yml` file:
```yaml
uglyUrls: true
```
2017-01-16 11:09:25 +00:00
## How do I enable streaming videos through the server?
You need to add this to your `config.yml` file:
```yaml
stream: true
```
Note that this can use a lot of ressources on your server.
## I want to download M3U videos
You need to enable streaming (see above).
## The downloaded videos have a strange name like `videoplayback.mp4`
AllTube can rename videos automatically if you enable streaming (see above).
2017-01-16 11:09:25 +00:00
## I want to download a video that isn't available in my country
2017-12-20 10:21:36 +00:00
If the video is available in the server's country,
you can download it if you enable streaming (see above).
2017-03-29 19:30:02 +00:00
## How do I run the Docker image?
```bash
docker run -p 8080:80 rudloff/alltube
```
## How do I run Heroku locally?
2017-03-12 11:26:33 +00:00
You should be able to use `heroku local` like this:
```bash
2017-12-20 10:21:36 +00:00
sudo APACHE_LOCK_DIR=. APACHE_PID_FILE=./pid APACHE_RUN_USER=www-data \
APACHE_RUN_GROUP=www-data APACHE_LOG_DIR=. \
heroku local
```
You might need to create some symlinks before that:
```bash
ln -s /usr/sbin/apache2 /usr/sbin/httpd
ln -s /usr/sbin/php-fpm7.0 /usr/sbin/php-fpm
```
2017-12-20 10:21:36 +00:00
And you probably need to run this in another terminal
after `heroku local` has finished launching `php-fpm`:
```bash
chmod 0667 /tmp/heroku.fcgi.5000.sock
```

## How can I download 1080p videos from Youtube?
Youtube distributes HD content in two separate video and audio files.
So AllTube will offer you video-only and audio-only formats in the format list.
2017-04-28 14:13:39 +00:00
You then need to merge them together with a tool like ffmpeg.
2017-12-20 10:21:36 +00:00
You can also enable the experimental remux mode
that will merge the best video and the best audio format on the fly.
## I want to convert videos to something other than MP3
By default the `convert` option only allows converting to MP3,
in order to keep things simple and ressources usage low.
However, you can use the `convertAdvanced` option like this:
```yaml
convertAdvanced: true
convertAdvancedFormats: [mp3, avi, flv, wav]
```
This will add new inputs on the download page
that allow users to converted videos to other formats.
