$1 is a subscription service which will index your media and allow voice-controlled playback on compatible smart speakers or Alexa apps.
The basic plan costs about 5 bucks a year and the server needn't be on a local computer; I've got ours running on a Raspberry Pi zero w (less than £10), with a 512GB card. Audiodescribed TV and film obviously can work without picture, rendering a typical episode of a show down to about 70 MB.
I tag TV series as audiobooks as far as mymedia is concerned, so it keeps your place in the season. Adding more episodes is just a copy and paste job, or a shell in and wget if I have a clear URL. I don't use it much anymore because all the stuff I watch is described on terrestrial or paid-for TV here in theUK and I watch with sighted family who want pictures, bless them
