hi,Mauro:
thanks for replying.
i am not sure the dtv api can be used in my project.because cmmb's
protocol is different to dmb :(
Then the API needs to be extended. Maybe by you. Correct me if I'm wrong,
but CMMB does not have standard MPEG2-TS and the configuration really
needs real-time constraints.
How does it work for your device?
To have proper support for non-MPEG2-TS DTV streams we could add a new
demuxer-type which handles it.
To tune a CMMB device we'd need to add the DTV_PROPERTIES to frontend.h
in Windows, we download firmware using windows driver,config fx2 as bulk
transfer,and read the TS stream,finally decode it and display.
I also read this post: "http://www.linuxjournal.com/article/7466"----
Writing a Real Driver?In User Space.
if i just want to read the ts stream,should i use this method? or another
way?
This option is rather useful for debugging/prototyping, IMO.
In the future we will have to support several CMMB device from different
manufacturers. Up to now, we have used the kernel-user-interface to have
stable API for different standards - we should continue to do so.
It would be nice to start the RFC-process for CMMB's extension to DVB API
5 .
