We don't need to do anything special, just keep calling record(), it should work.

thanks to reply. how can i solve the time gap between two file record, the time gap may call disconnect from rtmp server, finally make video pause at rtmp puller.

We can call setTimestamp() to whatever it needs it to be for that.

record.setTimestamp()? it means if i calculate timestamp in every frame by frame rate , the stream will be fluency？
