I think it might be a good idea to put this property in gstv4l2object.c (see the install/get/set_property_helper functions).. so that both v4l2sink and v4l2src get the property.

Typical GST_PTR_FORMAT usage goes as follows GST_LOG ("caps are %" GST_PTR_FORMAT, caps); GST_PTR_FORMAT seems to resolve to either "p" or "P" depending on preprocessor defs, with the idea that the GST debug system will introduce %p or %P as a new format flag for g_printerr() that will take the GType following the format string and format it accordingly. My problem is that this is not working in my windows builds. After further inspection, seems that in order for this to work, the GST debug system is using 'register_printf_specifier' on gstinfo.c to register the new format types and then after some massaging ends calling g_printerr() of GLib to do the final debug output. Seems like 'register_printf_specifier' is a glibc specific feature therefore is not available in any target that is not using glibc. This seems a little bit odd to me. Is GST_PTR_FORMAT really available only on glibc targets? thanks in advance, Alberto ------------------------------ ------------------------------------------------------------------------------ Download Intel&#174; Parallel Studio Eval Try the new software tools for yourself.
