How to set pts for raspivid stream

[Abu Abdullah]

Hi,

Raspberry Pi camera (raspivid) outputs a raw H264 stream, which has no
timing information. How to add pts to the pipeline to store it in mp4
format.

i tried may pipelines but non is working with me e.g.

raspivid -n -t 0 -w 640 -h 480 -fps 8 -pf high -o - | gst-launch-1.0
--gst-debug-level=2 -vvv fdsrc do-timestamp=true !
video/x-h264,width=640,height=480,framerate=8/1,stream-format=byte-stream
! h264parse ! splitmuxsink location=test_%03d.mp4
max-size-time=300000000

the error is:
/GstPipeline:pipeline0/GstSplitMuxSink:splitmuxsink0/GstFileSink:sink.GstPad:sink:
caps = video/quicktime, variant=(string)iso
