I'm here to help you understand how to configure the response format in the LiveKit egress service based on the type of output you're working with: • File Output (MP4, OGG): You can specify the format using the

file_type

parameter inside the

EncodedFileOutput

configuration. The supported formats are MP4 and OGG. • Stream Output (RTMP, SRT): The format depends on the

StreamProtocol

setting, which defines the streaming protocol, like RTMP. • Segmented File Output (HLS): This format is set through the

protocol

field within the

SegmentedFileOutput

configuration. • Track Egress: The format here is based on the encoding of the source video track, such as MP4, WebM, or OGG. If you're running into protobuf errors, it could be due to some mismatch in your configurations. I'd love to assist you further—could you please share a bit more about your current egress setup and the exact configuration you're using? That way, we can pinpoint the issue together and get things running smoothly.
