Thank you prompt reply.
I would record the source stream, and a reduced bitrate stream by transcode. According to your advice, I will do the ILiveStreamRecord.startRecordingSegmentByDuration in IMediaStreamActionNotify.onPublish to make sure all the transcoded stream start at the first frame.
Could you explain more about the option in transrate template so that both would be aligned? It sounds like an "non-transcoded" stream...
