Audio/video filters
The available options can depend on the version of the underlying encoding tools that Transloadit uses for the following Robots:
- 🤖/audio/artwork
- 🤖/audio/concat
- 🤖/audio/split
- 🤖/audio/encode
- 🤖/audio/loop
- 🤖/audio/merge
- 🤖/audio/waveform
- 🤖/meta/write
- 🤖/video/adaptive
- 🤖/video/artwork
- 🤖/video/concat
- 🤖/video/encode
- 🤖/video/merge
- 🤖/video/split
- 🤖/video/subtitle
- 🤖/video/thumbs
Transloadit recommends having: ffmpeg_stack: "v7" 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).
