웹캠 - xawtv 및 mplayer

모든 사람,

이상한 문제가 발생했습니다. 저는 Thinkpad t430에서 Debian Stretch를 실행하고 있습니다. 통합 웹캠을 사용하여 비디오를 캡처하려고 할 때

xawtv -c /dev/video0

내가 발행할 때보다

mplayer tv://

내가 얻는 오류는,

--> mplayer tv://

MPlayer interrupted by signal 11 in module: filter_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
 [ This binary of MPlayer in Debian is currently compiled with
   '--enable-debug'; the debugging symbols are in the package
   'mplayer-dbgsym'.]

위 오류로 인해 mplayer가 충돌하는 이유를 설명할 수 있는 사람이 있는데 xawtv에서 이를 표시할 수 있습니까?

문제를 디버깅하고 해결하는 데 도움을 주시면 대단히 감사하겠습니다.
