Sometimes splitmuxsink has high cpu load and prints "redistribute latency" message.

I have one usb video camera, that works with splitmuxsink very strange. This pipeline works well (writes data to mp4 file immediately): # timeout -s INT 60 gst-launch-1.0 \ > v4l2src device="/dev/video0" do-timestamp=true \ > ! image/jpeg,width=640,height=480,framerate=30/1 \ > ! jpegparse \ > ! omxmjpegdec \ > ! clockoverlay time-format="%Y-%m-%d %T" \ > ! videoconvert \ > ! omxh264enc target-bitrate=2097152 control-rate=variable interval-intraframes=30 \ > ! video/x-h264,profile=baseline \ > ! h264parse \ > ! mp4mux \ > ! filesink location="video.mp4" Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstSystemClock handling interrupt. Interrupt: Stopping pipeline ... Execution ended after 0:00:59.751358987 Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... # ls -l video.mp4 -rw-r--r-- 1 root root 733678 Jan 1 01:12 video.mp4 This pipeline loads cpu until first "redistribute latency" message (does not write any data to mp4 file during this time) and then has strange behavior: # timeout -s INT 300 gst-launch-1.0 \ > v4l2src device="/dev/video0" do-timestamp=true \ > ! image/jpeg,width=640,height=480,framerate=30/1 \ > ! jpegparse \ > ! omxmjpegdec \ > ! clockoverlay time-format="%Y-%m-%d %T" \ > ! videoconvert \ > ! omxh264enc target-bitrate=2097152 control-rate=variable interval-intraframes=30 \ > ! video/x-h264,profile=baseline \ > ! h264parse \ > ! splitmuxsink location="video-chunk-%02d.mp4" max-size-time=15000000000 Pipeline is live and does not need PREROLL ...

Do somebody have any ideas? What kind of logs should I attach?
