Aspect ratio changes not detected while watching H.264 SDTV

Description
H.264-encoded SDTV transmitted via IPTV changes its aspect ratio during playback like SDTV MPEG2 Streams transmitted via DVB.
MythTV 0.23-rc1 does not detect these changes. If you start watching a channel with a 4:3 program, and the channel changes to a 16:9 broadcast, MythTV continues playing with wrong 4:3 aspect - and vice versa of course.
It also affects playback of early started recordings. If a program or an ad block with different aspect precedes the recording target, it keeps the same wrong aspect ratio from the start of the recording during the complete playback.
This is due to a bug in FFmpeg described here and can be resolved by a minor patch:
