We are developing a video streaming platform. In that we want to encode video into H.264 format after uploading it.
We decided to use IBM Cloud Functions / OpenWhisk to encode the video, but having some doubts. Is it possible to upload a video file to IBM Cloud Functions / OpenWhisk and encode it? Is it supported, how can it be done?
Yes, that should be possible.
I recommend checking out this "Dark Vision" app using IBM Cloud Functions. You can upload videos which then are split into frames, the frames processed with Visual Recognition. The source code for Dark Vision is available on GitHub.
In addition you should go over the documented IBM Cloud Functions system limits to see if they match your requirements.
