During playback Airflow will transparently extract the text from picture subtitles and render it on target device just like it would with regular text subtitles. When comparing Azkaban and Luigi, you can also consider the following products Apache Airflow - Airflow is a platform to programmaticaly author, schedule and monitor data pipelines. You usually run Airflow in Docker Compose or Kubernetes. The workflow is running code, so migrating to a new version of Airflow is hard. It massively increases CPU load (think fan noise and heat) and it's completely infeasible to do for 4K videos.Įnter our new realtime subtitle text recognition (OCR). The Airflow library is frequently updated. This means that the only way to render them when streaming is to burn them in the video.
Some subtitles (DVD, Vobsub, Bluray) are stored as pictures. Integrated search is a cherry on top.with real time text recognition All widely used subtitle formats are supported, now including vobsub. Embedded or external, for our playback pipeline it's all the same. That involves reading the entire file upfront! Crazy, right? Airflow needs no such crude tricks. It's a bit of a secret that pretty much every other streaming software needs to extract embedded subtitle tracks before playing the video. For both embedded and external subtitles.
