#5004 closed defect (fixed)

remove string leak in VideoOutputDirectfb::GetRefreshRate()

Reported by: Erik Hovland <erik@…> Owned by: danielk

Description

When the env var FRAMEBUFFER can't be found in the environ list the member function then does a strdup("/dev/fb0"). This dynamically allocates a string that will have to be cleaned up later. This is never done, so this little bit of memory is leaked. Since getenv gives up a pointer from environ (that is a static, global list of strings) then it makes sense to just hand over a constant string at this point instead of a strdup of a constant string.

This defect was introduced in changeset:3720 from a patch given to the mythtv-dev list (at least four years ago).
