Fwd: [mythtv] 0.26 Beta build error in Crystal HD

[Richard Shaw]

Could anyone that helps maintain FFMpeg on RPM Fusion read Gary's
comments below and let me know if this is something we can fix or if I
need to disable CrystalHD support for MythTV 0.26.

Thanks,
Richard

My recollection is that FFmpeg itself gets these errors on Fedora
if compiled with crystalhd support, so it is not really surprising
that the same errors are seen for the MythTV FFmpeg port.  There
is clearly some version of headers mismatch between the FFmpeg
version of crystalhd support and Fedoras crystalhd version.  As
I recall, Gavin was looking at the header issue at some point, but
may never have been successful in finding matching versions, see:
http://www.gossamer-threads.com/lists/mythtv/users/516831

The person that did the crystalhd support for FFmpeg has gotten
other compilation error reports which he also suggests are due
to header version issues.

I suspect that crystalhd support will need to be disabled for
Fedora unless you get the problem accepted as a blocker
for 0.26.  I am not sure how many (if any) users that impacts.
