Other podcast players such as Apple Podcasts and steno.fm are pulling in the transcripts properly. However, on Pocket Casts, I get the error:

Sorry, but this transcript format is not supported: application/x-subrip

Step-by-step reproduction instructions

1. Begin to play "Spitball — Startup Ideas on Tap"

Hi @leoherzog ! Thanks for the report, I had a look and you are correct.

While we support the SRT format, we were expecting to see on the transcript type the following type: application/srt.

I investigated a bit and it looks that the application\x-subrip is also a valid mime type for SRT.

I will try to address this in the next release.

Awesome, thanks @SergioEstevao! I just learned about this myself from this week's Pocket Casts Partner Newsletter. The "technical details" link to the Podcasting 2.0 page about transcripts mentions:

Mime type of the file such as text/plain, text/html, text/vtt, application/json, application/x-subrip

😄
