[QtGstreamer] Howto extract GstValueList data from a QGlib::Value object?

[Yohan Pereira]

Hi,

How does one go about converting a QGLib::Value to a GstValueList or an equivalent data structure.

 

Heres the situation, I have added a level element which generates a message containing a GstValueList of gdoubles that represent the power levels for each channel. How do I access this data ? I am probably missing something very obvious here.

 

Thanks.

No, you are not missing something. Unfortunately, GstValueList support
is missing from QtGStreamer. Patches welcome :)
You can, of course, use the C api on the QGLib::Value directly.

Ahh I was afraid of that.

I *temporaily* resorted to parsing the string output using regex :D. It was just so easy to do but im probably better off with the C api.

 

Thanks for the reply.
