Mplayer
Материал из LinuxMCE Wiki.
Mplayer используется в LinuxMCE для проигрывания Blu-ray. Для того, чтобы система выбрала именно его, а не Xine, необходимо, чтобы расширение файла было .m2ts и его тип в медиа базе - LinuxMCE Blu-ray, а не LinuxMCE Video. В 0710 только с использованием mplayer можно проигрывать HD видео в формате MKV.

Параметры запуска mplayer
Судя по информации ps mplayer запускается в LinuxMCE со следующими параметрами при выбранном аппаратном ускорении VDPAU:
mplayer -slave -idle -msglevel all=4 -noborder -fixed-vo -fs -vo vdpau,xv -vc ffh264vdpau,ffmpeg12vdpau,ffvc1vdpau,ffwmv3vdpau -ao alsa:device=plug=dmix -ac a52, -lavdopts fast:threads=2 /usr/pluto/share/black.mpeg
где:
- -slave - переключает mplayer в slave mode для использования в качестве бэкенда для других программ, в частности LinuxMCE;
- -idle - используется совместно со slave mode, если нечего играть, то не выключается, а ждет команды от мастер-системы;
- -msglevel all=4 - устанавливает уровень информативности сообщений. В данном случае - informational messages;
- -noborder - убирает стандартное оформление окна;
- -fixed-vo - устанавливает режим, в котором выбранные видео файлы проигрываются в одном окне, а не каждый раз в новом. NOTE: в документации написано, что этот режим совместим с gl, gl2, mga, svga, x11, xmga, xv, xvidix and dfbmga. Про vdpau - ни слова;
- -fs - полноэкранный режим;
- -vo vdpau,xv - драйвера для вывода видео. В данном случае используется аппаратное ускорение vdpau и XVideo расширение XFree86 4.x;
- -vc ffh264vdpau,ffmpeg12vdpau,ffvc1vdpau,ffwmv3vdpau - список используемых видео кодеков;
- -ao alsa:device=plug=dmix - драйвера для вывода аудио. В данном случае, ALSA;
- -ac a52, - список используемых аудио кодеков;
- -lavdopts fast:threads=2 - список параметров для libavcodec. В данном случае используется параметр fast (MPEG-2, MPEG-4 и H.264), который включает оптимизацию, могущую как ускорить декодирование видео, так и вызвать проблемы при его воспроизведении, так как эта оптимизация не стандартизована. Примеры: simpler dequantization, simpler motion compensation, assuming use of the default quantization matrix, assuming YUV 4:2:0 and skipping a few checks to detect damaged bitstreams. Так же используется параметр threads, который определяет количество потоков для декодирования видео. В нашем случае, их будет два.

Проблемы с проигрыванием m2ts с vdpau
При проигрывании .m2ts файла (то же самое справедливо и для .mkv) mplayer в 0810 с акселерацией vdpau, нет ни картинки, ни звука. В логе можно увидеть следующие сообщения:

Решение проблемы
Возможным решением этой проблемы может стать добавление параметра -vf screenshot в строку запуска mplayer. По крайней мере, есть одни пример, когда это помогло.
