[Bug 1017734] Re: mythcommflag crashed with SIGSEGV in avcodec_decode_video2()

 

We really do appreciate you opening this ticket to help improve
Mythbuntu, but it needs to be closed for a number of reasons. The
biggest one is that upstream has moved on to a new version and believes
this to be fixed. Could you please verify if this issue still exists in
the latest version?

Please do not let the closing of this ticket dissuade you from opening a
new ticket if this (or any other) problem occurs with the newer
versions.
