День добрый.
На днях заметил что xine жрет 100% проца на ноутбуке (РIII-1133), решил
разобраться в чем дело. долго мучил его пересборками, ничего не помогло.
Выкопал libxine-1.1.0-alt2.1 собранный в январе, с ним все нормально, кушает
~16%. Не премудрствуя лукаво собрал libxine-1.1.1-alt2 на компакте, тоже все
нормально.
отличие в ключах gcc:
для компакта -mtune=pentium -mcpu=i686
для текущего сизифа -mtune=pentium4
причем на сизифе
%remove_optflags -mtune=pentium4
%add_optflags -mtune=pentium -mcpu=i686
совершенно ничего не дает.
дома на P-IV xine как работал нормально, так и работает
В общем назревает извечный вопрос
