Podcast tools

This repo keeps tracks of the tools and toolchains used to prepare Data Coffee podcast (mp3 files, shownotes and other artifacts).

Audio -> video pipeline

• create your audio as mp3 file with chapters integrated as metadata into the file
• run subgen: it takes snd.mp3 and prm.json as input -> generates sub.ass as output
• run ffmpeg: it takes snd.mp3 and sub.ass as input -> generates out.mp3 as output

New audio->video pipeline
