Comment (by mkver):

 1. Does it become slower and slower until it freezes or does it just
 freeze at an instant?
 2. If you encode to mp4 first and then remux this mp4 (no reencoding) to
 Matroska, does the same issue happen or not?
 3. If you use "-live 1" or output to stdout "-f matroska -", does the same
 issue still happen?
 4. Does Valgrind show anything useful?
 5. The Matroska muxer is very chatty with loglevel debug and higher; why
 did you not provide the output of this instead of only the ffmpeg -i
 <input> output (just use -report)?
 6. Have you tried using different (i.e. older) versions of FFmpeg?
