This project allows making Telegram group call using MtProto and WebRTC, this is possible thanks to the power of NodeJS's WebRTC library and [@evgeny-nadymov]

```

From H264/VP8/VP9 to Audio and Video
``` bash
ffmpeg -i {INPUT_FILE} -f s16le -ac 1 -ar {BITRATE} {OUTPUT_AUDIO_FILE} -f rawvideo -r {FRAMERATE} -pix_fmt yuv420p -vf scale={SCALING}:-1 {OUTPUT_VIDEO_FILE}
```

From YouTube video/live-stream to Audio and Video
``` bash
ffmpeg -i "$(youtube-dl -x -g "{YOUTUBE_LINK}")" -f s16le -ac 1 -ar {BITRATE} {OUTPUT_AUDIO_FILE} -f rawvideo -r {FRAMERATE} -pix_fmt yuv420p -vf scale={SCALING}:-1 {OUTPUT_VIDEO_FILE}
```

From YouTube Live stream to Video

> ### Important!
> The max resolution allowed by Telegram is of 720p at 30 fps
> Here also listed the scaling format
> - 360p = 640
> - 480p = 854
> - 720p = 1280
>
> If you have any problem with green screen or un-synchronized video, it can be one of these problems:
> - Invalid FFMPEG command
> - The video quality specified to convert is higher than the original video one
> - Invalid PyTgCalls video parameters
> - If you're using fifo, the Fifo max buffer size is too low and this cause the lag problem.
