Shots are currently processed synchronously for simplicity. This works fine for image because the processing is extremely minimal. Videos on the other hand have a higher processing requirement (exporting for HLS, multi-output bitrate, potentially padding the video to be compatible with HLS).
In order to keep things snappy, we need a better process for videos, heres what I am thinking:
- Synchronously export a lower quality HLS compatible version of the video (using the "ultrafast" preset), this will create a low quality version with distortions and such, but it will just be to keep the flow intact
- Dispatch a queued job chain to
- Export to multiple bitrates at slower presets (normal or something)
- Cleanup the old "fast" version that was created synchronous (can we just clobber this in the first step so users just start getting served this new version)
- Delete the source video
I definitely want to keep the ability to upload a shot and immediately get redirected to that video, wouldn't want a processing screen or anything like that if possible.
In order to make this happen, we will also need a queue setup (database driver should be fine for the moment), its possible we will also need to adopt supervisor or something similar to preserve the current single container approach.
