API

Currently there is no documentation about the interface. See the example app.py for the usage. The API is not finalized yet and can be changed without backward compatiblity in the future releases until v1.0.

For users since versions <0.20

VideoTransformerBase and its transform method have been marked as deprecated in v0.20.0. Please use VideoProcessorBase#recv() instead. Note that the signature of the recv method is different from the transform in that the recv has to return an instance of av.VideoFrame or av.AudioFrame. See the samples in app.py.
