[mythtv-users] Need help running MythTV on ARM NAS (LIBAVCODEC_52 error)

Thu Nov 20 11:06:11 UTC 2014

I can try.  Please confirm the minimum version of Qt required.  I have
4.7.4 compiled and I don't want to have to go through that again with a
newer version of Qt.

It'll take some time for me to try 0.27 since we have to make some
corrections to get it to work on our headless setup.  I'll report back...
