Chingari Highlights to Video

README.md

Description

This is a small script to automatically scrape the tranding section of the indian TikTok alternative Chingari. It uses ffmpeg to transcode and concatenate videos. As a performance optimization, cuvid and nvenc are used to offload work to the GPU which results in 5 to 10 times higher transcoding/concatenation speeds.

Required

• ffmpeg (built with nvenc and cuvid support
• Graphics Card supporting nvenc and cuvid
