--- Comment #25 from Jan Palus <jan.pa...@gmail.com> --- I experience the same issue (version 2.0.10). Seems like it starts to happen as soon as some glitch in decoding is encountered -- video artifacts, green screen which kaffeine recovers from within seconds but keeps on using 100% CPU. Following errors are logged then: [h264 @ 0x7fc1780ce820] top block unavailable for requested intra mode [h264 @ 0x7fc1780ce820] error while decoding MB 22 0, bytestream 26429 [h264 @ 0x7fc1780eae80] mmco: unref short failure [h264 @ 0x7fc1781069e0] mmco: unref short failure [h264 @ 0x7fc1780eae80] decode_slice_header error ...

It appears as if it goes into some notification loop (quite a lot of time is spent in mutex lock/unlock -- biggest self time).
