Comment:

 Also reproducible with
 {{{$ ffmpeg -i mmsh://livewms.europarl.europa.eu/reflector:52819 -f null
 -}}}
 The only working command line is
 {{{$ ffmpeg -i mmsh://livewms.europarl.europa.eu/reflector:52819 -map 0:25
 -map 0:26 -c copy out.mkv}}}

 The following commands work as expected:
 {{{$ ffplay -i mmsh://livewms.europarl.europa.eu/reflector:52819}}}
 {{{$ ffplay -i mmsh://livewms.europarl.europa.eu/reflector:52819 -ast 25
 -vst 26}}}
 Pressing "v" three times or pressing "a" 24 times while ffplay plackback
 also shows the problem.
