It seems that many contestants misunderstood the task. We are happy to provide clarifications regarding the task requirements, which you will find below.
Q: Can AVFoundation / VideoToolbox / CoreVideo be used?
A: Yes, anything that doesn't use AVPlayer to handle HLS playback is allowed.
Q: Are third party libraries/frameworks allowed (e.g. ffmpeg)?
A: Yes, anything that doesn't use AVPlayer to handle HLS playback is allowed.
Q: What do you mean by "switching between available video streams"?
A: The ability to change between different quality levels or versions of the video based on factors like network bandwidth or user selection. The player should be able to automatically switch to the most appropriate stream depending on the network conditions, or allow the user to manually select a stream which they prefer.
Q: Are there any minimum technical requirements for a video player? Which features are prioritized?
A: Video playback must be hardware-accelerated.
Q: Do we need support for offline playback?
A: No.
Q: Is it necessary to replace something specific in the source code of Telegram iOS from AVPlayer to our self-written player or all?
A: You only need to replace the relevant code in HLSVideoContent.swift where the AVPlayer is used for handling HLS streams
Q: Which formats and codecs should be supported with HLS and video decoding?
A: fmp4 / H264 / AAC.
Q: Will there be any guidelines on how switching between available qualities should be implemented on the UI/UX part?
A: The UI is already implemented. Quality switching is handled here.
🏆 Design Competition 2024, Round 2
Prize fund: Up to $30,000
Deadline: 23:59 Dubai time @ October 10th, 2024
Who can participate: Everyone
Telegram announces the next round of the competition for UI designers. The top prize is $4,000, and the winner may get a chance to join the Telegram Design team.
The Task is to create 2 (two) short demo videos for 2 different features in the same manner as the demonstrations from the Telegram Blog. Each video should offer a brief overview of a feature that currently does not exist in official Telegram apps:
Feature 1 – a general feature.
Feature 2 – a feature that is either a part of Telegram Premium or utilizes Telegram Stars.
Be creative, but don't get carried away by things like a major app redesign.
It is mandatory to cover both iOS and Android – 1 video out of 2 must be made for a different platform.
Evaluation Criteria:
While evaluating submissions, the judges may apply the following criteria to determine the winners:
Alignment – the video must be as close as possible to the ones from the Telegram Blog.
Clarity – the general audience must have a clear understanding of how the feature you are displaying works.
Consistency – the video should be looped, with smooth transitions between screens and all elements should be consistent and balanced.
Completeness – you must present a finalized flow for your feature. Your video should show an entry point from existing Telegram interfaces, a brief overview of the feature's main components and a transition back to the entry point.
🏆 Telegram Contest for JavaScript Developers, Round 2: Results
We were pleased to see both participants from Round 1 and those who joined the Telegram Contests for the very first time! The Contest Task, which covered multiple areas of the app (implementing a new feature, adding another feature that heavily relies on the existing codebase, and fixing an obscure issue), proved to be particularly challenging for the contestants, with no one completing all three tasks.
Most contestants focused on the Media Editor, so the judges adjusted their evaluation accordingly. After many hours of testing, we are pleased to confirm that Hip Hyena secured 🥇1st PLACE by delivering the best media editor among all the submissions. This time, given the input each contestant contributed, we will reward everyone who implemented at least one contest task, even if their implementation wasn't perfect.
Meet the winners!
1st PLACE – $10,000
🥇Hip Hyena
2nd PLACE – $3,000
🥈Tall Lynx
🥈Nice Elk
3rd PLACE – $2,000

🏆 Telegram Contest for JavaScript Developers, Round 2
Prize fund: $30,000
Deadline: 23:59 on July 28th (Dubai time)
Who can participate: Everyone is welcome to participate, even if they didn't take part in the previous round
Results: August 18th, 2024
Telegram is hosting a contest for JavaScript developers to implement two new features into Telegram Web and address the scrolling issue on Chrome for Android.
The Task:
1. Implement Media Editor and Multiple Accounts into Telegram Web K based on the provided mockups.
2. Web K is currently experiencing scrolling issues when used on Chrome for Android. This issue causes noticeable lagging on devices with 120 FPS displays, particularly when scrolling through any entities containing numerous media elements – essentially, any channel with larger message bubbles and multiple media items. (You must investigate the issue, provide a detailed explanation of it, and implement a fix that will address the issue.)
Evaluation Criteria and Requirements:
General
– No third-party UI frameworks are allowed.
– The submission must be consistent with the existing Web K codebase.
– Your implementation must work flawlessly on desktop Chrome (across Linux, macOS, Windows) and Safari on macOS. Proper support for other browsers and mobile environments (Android, iOS) will be considered a bonus.
❗️Your app must precisely follow the provided design mockups. Entries that fail to do so will be severely penalized.
Further Clarifications:
Media Editor
– You must not use any libraries or components (i.e., from other existing media editors) for any parts of the Media Editor. All the features presented in the mockups must be built from scratch.
– It is acceptable to send static media when an animated sticker is added to a photo, though a proper conversion into a GIF would be considered a bonus.
Multiple Accounts
The app must properly handle the databases from several accounts, support simultaneous notifications, and oversee all possible edge cases, including forced logout from another device. For reference, you may check official Telegram apps.
Submissions:
Contestants will be able to submit their entries to @ContestBot at a later date. We will further clarify the submission instructions closer to the deadline.
P.S. Winners may be offered a chance to explore further opportunities with Telegram.
Design Competition 2024: Submissions
We received 185 submissions for the Design Competition.
Everyone is welcome to view the submissions while the Telegram judges conduct their own checks.
ContestBot is now ready to accept submissions for the Design Competition.

- An archive containing all your videos in their original resolution. Optionally, you may also include source files for your project (e.g., .aep files).
Note: Your channel may stay private until the deadline. Make sure you assign it a username after the deadline.
🏆 Telegram Сontest for JS Developers, Round 1: Results
After many hours of testing and watching hundreds of Live Streams, we are now ready to announce the results. From a total of 19 submissions, 13 contestants qualified for prizes – basically every developer who implemented at least one part of the overall task.
Despite a challenging Contest Task and a tight deadline, we were happy to see many solid apps. Despite nobody achieving perfect Live Streams (each implementation we tested requires a significant amount of further polishing), we would like to give a special thanks to🥇Fit Whale, who was able to find a great minimalist solution for Task II that will be merged with Web K soon.🥈Dreamy Crow presented a similar approach that is slightly less optimal, but still notable.
Meet the winners!
1st PLACE – $6,000
🥇Fit Whale
2nd PLACE – $3,000
🥈Dreamy Crow
🥈Hip Hyena
🥈Large Moth
🥈Sweet Yak

Your implementation must remove any story-related restrictions or controls. Specifically, your app must not impose a limit on video length and should exclude interface controls that are only relevant for stories. Your app must retain the existing in-chat camera interface and flow before user opens the camera (i.e., the preview within the attachment menu).
Contest Requirements:
General
– Your app must provide a consistent and smooth recording experience that aligns with the device's native camera app.
– No third-party UI frameworks are allowed.
– The submission must be consistent with the existing Telegram for Android codebase.

Note:
Submissions that introduce improvements to video recording are likely to receive higher scores in this contest.
Evaluation:
During the evaluation stage, we will review your code and test the submission on a wide range of Android devices.
Winners may be offered a chance to join the 🛫 Telegram Team.
Submissions:
Contestants will be able to submit their entries to @ContestBot at a later date. We will further clarify the submission instructions closer to the deadline.

🏆 Design Competition 2024: Results
This was by far the most thrilling design contest we've ever held! We would like to express our sincerest gratitude and admiration to each and every contestant – both those who took their very first steps in the challenging world of design and the noble design veterans who set aside some time from their projects to contribute to a better Telegram of tomorrow. ✨
You all are amazing, and we thank you a lot for your fantastic designs! 💙
Now, let us shed some light on the judging process in this competition. The Telegram Design Team joined forces with the Telegram Contest Department, and each judge spent dozens of hours watching and sorting through all the submissions. Once the judges completed their solo evaluations and highlighted the most promising discoveries, the whole jury met to watch and discuss together all the submissions that were not instantly discarded. Aside from the initially mentioned core criteria, another important consideration was, "How close is this video to the ones we make for Telegram Blog?" 🏅
Thanks to this multistage checking, verification, and discussions, the members of the jury were unanimous in the prize distribution.
⚠️ We’ve noticed that many participants uploaded their videos as files to their contest channels.
This is not the right way – the channel should host your demos sent as VIDEOS. ✔️
Make sure to address this before the deadline. (For reference, see @TelegramTips.)
🏆 Design Competition 2024
Prize fund: Up to $30,000
