## Overview
This package uses the **[FFmpeg](https://ffmpeg.org)** to package media content for online streaming such as DASH and HLS. You can also use **[DRM](https://en.wikipedia.org/wiki/Digital_rights_management)** for HLS packaging. There are several options to open a file from a cloud and save files to clouds as well.
- **[Full Documentation](https://video.aminyazdanpanah.com/python/)** is available describing all features and components.
- In this version(>=v0.1.0) all codes are rewritten from scratch. If you find any bugs in the library, please **[file an issue](https://github.com/aminyazdanpanah/python-ffmpeg-video-streaming/issues)**. **[Pull requests](https://github.com/aminyazdanpanah/python-ffmpeg-video-streaming/pulls)** are also welcome.

## Requirements
1. This version of the package is only compatible with **[Python 3.8](https://www.python.org/downloads/)** or higher.
2. To use this package, you need to **[install the FFmpeg](https://ffmpeg.org/download.html)**. You will need both FFmpeg and FFProbe binaries to use it.
## Installation
Install the package via **[pip](https://pypi.org/project/pip/)**:
```bash
pip install python-ffmpeg-video-streaming
```
Alternatively, add the dependency directly to your `requirements.txt` file:
```txt
python-ffmpeg-video-streaming>=0.1
```
## Quickstart
First of all, you need to import the package in your code:
```python
import ffmpeg_streaming2
```
### Opening a Resource
There are several ways to open a resource.
#### 1. From an FFmpeg supported resource
You can pass a local path of video(or a supported resource) to the `input` method:
```python
video = ffmpeg_streaming2.input('/var/media/video.mp4')
```
See **[FFmpeg Protocols Documentation](https://ffmpeg.org/ffmpeg-protocols.html)** for more information about supported resources such as HTTP, FTP, and etc.
**For example:**
```python
video = ffmpeg_streaming2.input('https://www.aminyazdanpanah.com/?"PATH TO A VIDEO FILE" or "PATH TO A LIVE HTTP STREAM"')
```
#### 2. From Clouds
You can open a file from a cloud by passing an instance of the Cloud object to the `input` method.
```python
from ffmpeg_streaming2 import S3
s3 = S3(aws_access_key_id='YOUR_KEY_ID', aws_secret_access_key='YOUR_KEY_SECRET', region_name='YOUR_REGION')
video = ffmpeg_streaming2.input(s3, bucket_name="bucket-name", key="video.mp4")
```
Visit **[this page](https://video.aminyazdanpanah.com/python/start/clouds?r=open)** to see some examples of opening a file from **[Amazon S3](https://aws.amazon.com/s3)**, **[Google Cloud Storage](https://console.cloud.google.com/storage)**, **[Microsoft Azure Storage](https://azure.microsoft.com/en-us/features/storage-explorer/)**, and a custom cloud.
#### 3. Capture Webcam or Screen (Live Streaming)
You can pass the name of a supported, connected capture device(i.e. the name of a webcam, camera, screen and etc) to the `input` method to stream a live media over the network from your connected device.
```python
capture = ffmpeg_streaming2.input('CAMERA NAME OR SCREEN NAME', capture=True)
```
To list the supported, connected capture devices, see **[FFmpeg Capture Webcam](https://trac.ffmpeg.org/wiki/Capture/Webcam)** and **[FFmpeg Capture Desktop](https://trac.ffmpeg.org/wiki/Capture/Desktop)**.
### DASH
**[Dynamic Adaptive Streaming over HTTP (DASH)](http://dashif.org/)**, also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high-quality streaming of media content over the Internet delivered from conventional HTTP web servers. [Learn more](https://en.wikipedia.org/wiki/Dynamic_Adaptive_Streaming_over_HTTP)
Create DASH files:
```python
from ffmpeg_streaming2 import Formats
dash = video.dash(Formats.h264())
dash.auto_generate_representations()
dash.output('/var/media/dash.mpd')
```
Generate representations manually:
```python
from ffmpeg_streaming2 import Formats, Bitrate, Representation, Size
_144p = Representation(Size(256, 144), Bitrate(95 * 1024, 64 * 1024))
_240p = Representation(Size(426, 240), Bitrate(150 * 1024, 94 * 1024))
_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))
_1080p = Representation(Size(1920, 1080), Bitrate(4096 * 1024, 320 * 1024))
_2k = Representation(Size(2560, 1440), Bitrate(6144 * 1024, 320 * 1024))
_4k = Representation(Size(3840, 2160), Bitrate(17408 * 1024, 320 * 1024))
dash = video.dash(Formats.h264())
dash.representations(_144p, _240p, _360p, _480p, _720p, _1080p, _2k, _4k)
dash.output('/var/media/dash.mpd')
```
See **[DASH section](https://video.aminyazdanpanah.com/python/start?r=dash#dash)** in the documentation, for more examples.
### HLS
**[HTTP Live Streaming (also known as HLS)](https://developer.apple.com/streaming/)** is an HTTP-based adaptive bitrate streaming communications protocol implemented by Apple Inc. as part of its QuickTime, Safari, OS X, and iOS software. Client implementations are also available in Microsoft Edge, Firefox, and some versions of Google Chrome. Support is widespread in streaming media servers. [Learn more](https://en.wikipedia.org/wiki/HTTP_Live_Streaming)
Create HLS files:
```python
from ffmpeg_streaming2 import Formats
hls = video.hls(Formats.h264())
hls.auto_generate_representations()
hls.output('/var/media/hls.m3u8')
```
Generate representations manually:
```python
from ffmpeg_streaming2 import Formats, Bitrate, Representation, Size
_360p = Representation(Size(640, 360), Bitrate(276 * 1024, 128 * 1024))
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
_720p = Representation(Size(1280, 720), Bitrate(2048 * 1024, 320 * 1024))
hls = video.hls(Formats.h264())
hls.representations(_360p, _480p, _720p)
hls.output('/var/media/hls.m3u8')
```
See **[HLS section](https://video.aminyazdanpanah.com/python/start?r=hls#hls)** in the documentation, for more examples such as Fragmented MP4, live from camera/screen and so on.
#### Encryption(DRM)
The encryption process requires some kind of secret (key) together with an encryption algorithm. HLS uses AES in cipher block chaining (CBC) mode. This means each block is encrypted using the ciphertext of the preceding block. [Learn more](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation)
You must specify a path to save a random key to your local machine and also a URL(or a path) to access the key on your website(the key you will save must be accessible from your website). You must pass both these parameters to the `encryption` method:
##### Single Key
The following code generates a key for all segment files.
```python
from ffmpeg_streaming2 import Formats
#A path you want to save a random key to your local machine
save_to = '/home/public_html/"PATH TO THE KEY DIRECTORY"/key'
#A URL (or a path) to access the key on your website
url = 'https://www.aminyazdanpanah.com/?"PATH TO THE KEY DIRECTORY"/key'
# or url = '/"PATH TO THE KEY DIRECTORY"/key';
hls = video.hls(Formats.h264())
hls.encryption(save_to, url)
hls.auto_generate_representations()
hls.output('/var/media/hls.m3u8')
```
##### Key Rotation
An integer as a "key rotation period" can also be passed to the `encryption` method (i.e. `encryption(save_to, url, 10)`) to use a different key for each set of segments, rotating to a new key after this many segments. For example, if 10 segment files have been generated then it will generate a new key. If you set this value to **`1`**, each segment file will be encrypted with a new encryption key. This can improve security and allows for more flexibility.
See **[the example](https://video.aminyazdanpanah.com/python/start?r=enc-hls#hls-encryption)** for more information.
**IMPORTANT:** It is very important to protect your key(s) on your website. For example, you can use a token(using a Get/Post HTTP method or add a token to authorization header) to check if the user is eligible to access the key or not. You can also use a session(or cookie) on your website to restrict access to the key(s)(**It is highly recommended**).
##### DRM
However FFmpeg supports AES encryption for HLS packaging, which you can encrypt your content, it is not a full **[DRM](https://en.wikipedia.org/wiki/Digital_rights_management)** solution. If you want to use a full DRM solution, I recommend trying **[FairPlay Streaming](https://developer.apple.com/streaming/fps/)** solution which then securely exchange keys, and protect playback on devices.
**Besides [Apple's FairPlay](https://developer.apple.com/streaming/fps/)** DRM system, you can also use other DRM systems such as **[Microsoft's PlayReady](https://www.microsoft.com/playready/overview/)** and **[Google's Widevine](https://www.widevine.com/)**.
### Transcoding
You can get realtime information about the transcoding using the following code.
```python
from ffmpeg_streaming2 import Formats
import sys
def monitor(ffmpeg, duration, time_, time_left, process):
"""
Handling proccess.
Examples:
1. Logging or printing ffmpeg command
logging.info(ffmpeg) or print(ffmpeg)
2. Handling Process object
if "something happened":
process.terminate()
3. Email someone to inform about the time of finishing process
if time_left > 3600 and not already_send: # if it takes more than one hour and you have not emailed them already
ready_time = time_left + time.time()
Email.send(
email='someone@somedomain.com',
subject='Your video will be ready by %s' % datetime.timedelta(seconds=ready_time),
message='Your video takes more than %s hour(s) ...' % round(time_left / 3600)
)
already_send = True
4. Create a socket connection and show a progress bar(or other parameters) to your users
Socket.broadcast(
address=127.0.0.1
port=5050
data={
percentage = per,
time_left = datetime.timedelta(seconds=int(time_left))
}
)
:param ffmpeg: ffmpeg command line
:param duration: duration of the video
:param time_: current time of transcoded video
:param time_left: seconds left to finish the video process
:param process: subprocess object
:return: None
"""
per = round(time_ / duration * 100)
sys.stdout.write(
"\rTranscoding...(%s%%) %s left [%s%s]" %
(per, datetime.timedelta(seconds=int(time_left)), '#' * per, '-' * (100 - per))
)
sys.stdout.flush()
hls = video.hls(Formats.h264())
hls.auto_generate_representations()
hls.output('/var/media/hls.m3u8', monitor=monitor)
```
##### Output From a Terminal:
### Saving Files
There are several ways to save files.
#### 1. To a Local Path
You can pass a local path to the `output` method. If there is no directory, then the package will create it.
```python
from ffmpeg_streaming2 import Formats
dash = video.dash(Formats.h264())
dash.auto_generate_representations()
dash.output('/var/media/dash.mpd')
```
It can also be None. The default path to save files is the input directory.
```python
from ffmpeg_streaming2 import Formats
hls = video.hls(Formats.h264())
hls.auto_generate_representations()
hls.output()
```
**NOTE:** If you open a file from a cloud and do not pass a path to save the file to your local machine, you will have to pass a local path to the `output` method.
#### 2. To Clouds
You can save your files to a cloud by passing an instance of a `CloudManager` to the `output` method.
```python
from ffmpeg_streaming2 import S3, CloudManager
s3 = S3(aws_access_key_id='YOUR_KEY_ID', aws_secret_access_key='YOUR_KEY_SECRET', region_name='YOUR_REGION')
save_to_s3 = CloudManager().add(s3, bucket_name="bucket-name")
hls.output(clouds=save_to_s3)
```
A path can also be passed to save a copy of files to your local machine.
```python
hls.output('/var/media/hls.m3u8', clouds=save_to_s3)
```
Visit **[this page](https://video.aminyazdanpanah.com/python/start/clouds?r=save)** to see some examples of saving files to **[Amazon S3](https://aws.amazon.com/s3)**, **[Google Cloud Storage](https://console.cloud.google.com/storage)**, **[Microsoft Azure Storage](https://azure.microsoft.com/en-us/features/storage-explorer/)**, and a custom cloud.
**NOTE:** This option is only valid for **[VOD](https://en.wikipedia.org/wiki/Video_on_demand)** (it does not support live streaming).
**Schema:** The relation is `one-to-many`
<p align="center"><img src="https://github.com/aminyazdanpanah/aminyazdanpanah.github.io/blob/master/video-streaming/video-streaming.gif?raw=true" width="100%"></p>
#### 3. To a Server Instantly
You can pass a URL(or a supported resource like `FTP`) to the `output` method to upload all the segments files to the HTTP server(or other protocols) using the HTTP PUT method and update the manifest files every refresh times.
```python
# DASH
dash.output('http://YOUR-WEBSITE.COM/live-stream/out.mpd')
# HLS
hls.save_master_playlist('/var/media/hls.m3u8')
#Before running the following code, you should upload the master playlist to the server. For example upload the '/var/media/hls.m3u8' to 'ftp://[user[:password]@]server[:port]/var/media/hls.m3u8'
hls.output('ftp://[user[:password]@]server[:port]/var/media/hls.m3u8')
```
See **[FFmpeg Protocols Documentation](https://ffmpeg.org/ffmpeg-protocols.html)** for more information about supported resources.
### Metadata
You can get information from the video file using the following code.
```python
from ffmpeg_streaming2 import FFProbe
ffprobe = FFProbe('/var/media/video.mp4')
```
See **[the example](https://video.aminyazdanpanah.com/python/start?r=metadata#metadata)** for more information.
### Conversion
You can convert your stream to a file or to another stream protocol. You should pass a manifest of the stream to the `input` method:
#### 1. HLS To DASH
```python
from ffmpeg_streaming2 import Formats, Bitrate, Representation, Size
video = ffmpeg_streaming2.input('https://www.aminyazdanpanah.com/?PATH/TO/HLS-MANIFEST.M3U8')
_480p = Representation(Size(854, 480), Bitrate(750 * 1024, 192 * 1024))
dash = video.dash(Formats.h264())
dash.representations(_480p)
dash.output('/var/media/dash.mpd')
```
#### 2. DASH To HLS
```python
video = ffmpeg_streaming2.input('https://www.aminyazdanpanah.com/?PATH/TO/DASH-MANIFEST.MPD')
hls = video.hls(Formats.h264())
hls.auto_generate_representations()
hls.output('/var/media/hls.m3u8')
```
#### 3. Stream(DASH or HLS) To File
```python
video = ffmpeg_streaming2.input('https://www.aminyazdanpanah.com/?PATH/TO/MANIFEST.MPD or M3U8')
stream = video.stream2file(Formats.h264())
stream.output('/var/media/new-video.mp4')
```

## FAQs
**I created stream files and now what should I pass to a player?**
You must pass a **master playlist(manifest) URL**(e.x. `https://www.aminyazdanpanah.com/?"PATH TO STREAM DIRECTORY"/dash-stream.mpd` or `/PATH_TO_STREAM_DIRECTORY/hls-stream.m3u8` ) to a player.
See the demo page of these players for more information(**[hls.js Demo](https://hls-js.netlify.app/demo/)**, **[dash.js Demo](https://reference.dashif.org/dash.js/v3.1.2/samples/dash-if-reference-player/index.html)**, **[videojs Demo](https://videojs.com/advanced?video=elephantsdream)** and etc).
**My player does not show the quality selector button to change the video quality?**
Some Players do not have an embedded quality selector button to change this option and you should install(or add) the plugin for this use case. For example, if you are using Videojs to play your stream, you can install **[videojs-hls-quality-selector](https://github.com/chrisboustead/videojs-hls-quality-selector)** to show the quality selector. For adding a plugin to other players, you can easily Google it!
**I uploaded my stream files to a cloud but it does not play on my website?**
If you save your stream content to a cloud(i.e. **[Amazon S3](https://aws.amazon.com/s3)**), make sure your contents are **PUBLIC**. If they are not, you must change the access control.
**Does [IOS](https://www.apple.com/ios) support the DASH stream?**
No, IOS does not have native support for DASH. Although there are some libraries such as **[Viblast](https://github.com/Viblast/ios-player-sdk)** and **[MPEGDASH-iOS-Player](https://github.com/MPEGDASHPlayer/MPEGDASH-iOS-Player)** to support this technique, I have never tested them. So maybe some of them will not work properly.
