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. 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).
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 Launch the Terminal app (macOS, Linux) and type the following command, replacing IP ADDRESS with your Chromcast's IP address: Press Enter. All widely used subtitle formats are supported, now including vobsub. To try and force an update via a Mac or Linux PC, power on your machine and ensure it's connected to the same Wi-Fi network as your Chromecast dongle. 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.
