Hey everyone! I’m trying to figure out how to make my Telegram bot turn regular videos into those cool circular video notes. You know, the ones that play in a loop?
I’ve got this basic code set up:
@router.message(Command('make_circle'))
async def create_circle(message: Message):
await message.reply_video_note(video_note='some_video_id')
Right now, it just sends back a pre-existing video note. But what I really want is for the bot to take a video the user uploads, convert it into a circular video note, and then send that back to the chat.
Has anyone done this before? Are there any libraries or methods in Aiogram 3.11 that can help with this video conversion? I’d really appreciate any tips or code examples you could share. Thanks in advance!
As someone who’s implemented this feature before, I can tell you it’s definitely possible but requires a bit of work. You’ll need to use a library like OpenCV or Pillow to process the video frames. Here’s a rough outline:
- Download the user’s video
- Extract frames
- Create a circular mask
- Apply the mask to each frame
- Reassemble the frames into a video
- Send as video_note
The trickiest part is getting the circular crop just right. You might need to experiment with different resolutions and crop sizes to meet Telegram’s requirements.
One gotcha to watch out for: make sure your final video meets Telegram’s specs for video notes (square aspect ratio, specific file size limits, etc.). Otherwise, it might not play properly.
Good luck with your project! Let me know if you need any more specific advice.
hey olivias! i’ve actually done something similar before. you’ll need to use ffmpeg for video processing. first, download the user’s video, then use subprocess to run ffmpeg commands to crop and convert it. finally, send the new file as a video note. it’s a bit tricky but doable!
To create circular video notes from user-uploaded videos, you’ll need to implement a few additional steps in your bot’s workflow.
First, ensure you have a handler to receive and download the user’s video file. Then, utilize a video processing library like MoviePy or FFmpeg to crop and resize the video into a circular format. This may involve creating a circular mask and applying it to each frame.
Once processed, you can send the resulting file as a video note using the send_video_note method. Keep in mind that Telegram has specific requirements for video notes, such as a 1:1 aspect ratio and maximum duration. You might need to adjust your processing parameters accordingly.
Remember to handle potential errors, such as unsupported file formats or processing failures, to provide a smooth user experience.
