Video streaming for Voice Chats in the next Telegram update!

It will be possible to broadcast not only the camera, but also the screen capture! Source: Durov’s post

Should I add the ability to stream video for pytgcalls?)

pytgcalls updated. Added macOS wheels and the last data source — devices

Available sources of input/output data transfers:
- File (playout example, recording example) — to use any audio files including named pipe (FIFO).
- Device (example) — to use microphone, headphones, etc.
- Raw (example) — to send and receive data in bytes directly from Python.

Available macOS wheels:
- Intel. Sierra+, Python 3.6-3.9.
- Apple Silicon (M1). Big Sur, Python 3.9.

Feel free to contribute into GitHub workflow for building wheels for Windows. The biggest part are already ready. More info here…

Удачи ❤️

Group video calls almost here!

Screen sharing, video from camera and video pins. Available in macOS beta, @macswift chat

More high-resolution screenshots in comments

In the next update, it will be possible to disable audio processing!

This has long been done in the MarshalX/tgcalls library, but is now available in the official macOS beta client. That allows you to stream audio in good quality through a virtual device. The bitrate still cannot be controlled.

Testing video calls in chats

Previously, the ability to test video calls on beta versions of clients was only possible in two chats: Unigram and macOS.

Now this opportunity has appeared in the @tgcallschat ✨

To enable video calls in your chat you need to add the hashtag #vid to the title of your voice chat. Only available on beta clients with video calls support!

Currently, video chats are supported in beta versions of Unigram and macOS clients.

Video calls will be limited by 30 participants at first release

More people won't be able to watch video broadcasts or turn on their stream 🤷

Telegram fixed a new type of spam via invitations to voice chat

There were 2 main problems with MTProto phone.InviteToGroupCall method:
1. The server did’t limit the count and frequency of sent requests in any way. These led to sending a large count of service messages to the chat in one second.
2. Restriction by invitation of the same person was not implemented on the server side. Which allowed to invite one person a thousand times.

After reporting these issues tonight, they were resolved. Corresponding errors have appeared
1. [420 FLOOD_WAIT_X]: A wait of 48 seconds is required (caused by "phone.InviteToGroupCall")
2. [400 Bad Request]: [400 USER_ALREADY_INVITED] (caused by "phone.InviteToGroupCall)

Due to the count of invites I sent during the test, workers of Telegram servers went to restart 🤷
