I am looking for a video file transcoding solution that I can run on an on-premises server and access via a REST API.
While I found lots of commercial cloud services (e.g. https://www.filestack.com/products/audio-video-transformations/ or https://zencoder.com/en/), I could not find an on-premises video transcoding server, neither open source nor commercial.
Do you have recommendations? Do you use a custom built solution?
