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
0:00:08.480968094  2314  0x15678f0 WARN                   qtmux

Use Jan's rpicamsrc element from here:

https://github.com/thaytan/gst-rpicamsrc/

It uses the same interface as raspivid, just from inside a GStreamer
element.

Thank you for your response. 

Is there a way to do it with normal pipeline. I tried rpicamsrc previously but found it not practical in my case. 

Thank you

scanning the code of rpicamsrc, it seems it sets gst_pts to
GST_CLOCK_TIME_NONE. the problem with the normal pipeline is the
missing pts. is there any way to set the pts to none in the normal
pipeline. i have seen some threads about setting pts from dts in
h264parse.

is there a way to overcome this with a standard pipeline
