• PHP queue implementation

  2 mars 2015, par Ben

  I’m new to using queues for intensive processes. I have an app that will take an upload of a short video, process it with FFMPEG, then upload to youtube using their API, then interact with my database. My questions :

  Should I use two different queues ? One to process, then hand it off to a different queue to upload ? Or should I place all my processing in one worker ?

  Is it ok to interact with a database from a worker or should I do this some other way ?

  The stream that that is pushed the stream into nginx looks great ! But the nginx recording looks very granny and pixelated. What could be causing the loss in quality as nginx records the stream ?
