Without your vidix, and no scaling, it takes 64% of CPU for both audio and video decoding, and plays fine. If I use your vidix library, I only get a black screen. The black screen includes a cursor blinking at the bottom line, as there was before running mplayer. Using the software scaler, it does not have enough cpu. I run mplayer from a ssh from my PC. Maybe I have to specify /dev/fb0 somewhere? Here comes the play log: vidix: managed to load jz47xx_vid.so registering jz47xx_drv (0x2bba0a30) registered jz47xx_drv (0x2bba0a30) probing jz47xx...jz47xx: Using JZ4740 FB on 320x240 32 bpp /dev/fb0 ========================================================================== Forced video codec: fftheora Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [fftheora] vfm: ffmpeg (FFmpeg Theora) ========================================================================== ========================================================================== Forced audio codec: tremor Opening audio decoder: [tremor] Ogg/Vorbis audio decoder AUDIO: 48000 Hz, 2 ch, s16le, 64.0 kbit/4.17% (ratio: 8000->192000) Selected audio codec: [tremor] afm: tremor (OggVorbis audio) ========================================================================== [AO OSS] audio_setup: Can't open audio device /dev/dsp: No such file or directory AO: [alsa] 48000Hz 2ch s16le (2 bytes per sample) Starting playback...
