Audio codecs
The particular set of Audio Codecs that you can use can depend on the version of the underlying encoding tools that Transloadit uses for the following Robots:
- 🤖/audio/artwork
- 🤖/audio/concat
- 🤖/audio/encode
- 🤖/audio/loop
- 🤖/audio/merge
- 🤖/meta/write
- 🤖/video/concat
- 🤖/video/encode
- 🤖/video/merge
- 🤖/video/subtitle
- 🤖/video/thumbs
Transloadit recommends having:
ffmpeg_stack: "v6.0.0" in these Robots'
Assembly Instructions. We are intimately aware of how important continuity is for our
customers, so stack version upgrades are always opt-in.
Stack versions are typically supported for many years before we start issuing deprecation warnings
(for example: we had been supporting "v1.0.0" for 11 years before we deprecated it).
