Comment (by Kirill A. Korinsky):

 MasterQuestionable, if it is only OS/env bug, when the picture should
 unfreeze as soon as I enforce the high speed in CPU, isn't it?

 Right now I see that if I start streaming by ffplay with CPU speed in 1600
 MHz or more, it works, but as soon as I switched to slower speed... the
 picture is frozen, and switch back to higher CPU speed does not unfreeze
 the picture.

 It really looks like that ffplay / ffmpeg has an issue on this stream, and
 some missed frames due to "slow CPU" leads to frozen picture completley,
 and `-noframedrop` prevents it.
