TeleSpy

Added mega to upload large files.

• Breaking Change

• Completely removing OpenCV and PyAudio for recording from webcam and microphone and using ffmpeg CLI for all the things e.g. taking photo, video and audio. It's much faster and doesn't require any post-processing and muxing. The OpenCv version is still available although in a separate branch.

Initial release. Supports the following commands
1. /photo - Take a temporary photo
2. /audio - Take audio
3. /video - Take video
4. /photo_keep - Take and keep photo
4. /videoonly - Take video without audio
Large video files will be split as per telegram restriction.
