At work I have to deal with videos in different resolutions. We're also switching from H.264 to AV1, so I needed a quick way to test our video pipeline with different formats and sizes. I created lorem.video - a service that generates placeholder videos directly from the URL. For example: https://lorem.video/1280x720_h264_20s_30fps You control everything via the URL path: resolution, duration, codec (h264/h265/av1/vp9), bitrate, and fps. Videos are cached after first generation, so subsequent requests are instant. Built it in Go using FFmpeg for encoding. Generation runs in a nice'd process so it doesn't interfere with serving cached videos. Running on a cheap VPS. MIT licensed, source on GitHub: https://github.com/guntisdev/lorem-video |
