DM8168 unrecoverable error: OMX_ErrorBadParameter (0x80001005) [resolved]

DM8168 custom board 成功啟動(dòng)系統(tǒng)以后想先測1下8168編解碼功能，把開發(fā)包里的examples跑1遍。啟動(dòng)完成后，連上HDMI顯示，在starting Matrix GUI application后HDMI已有輸出了，這時(shí)候候優(yōu)先選擇了decode_display功能來測試。

想了好久，查了很多，最后想到了要改變分辨率。

root@8168:~#sh change_resolution.sh 1080p60

修改分辨率成功后，reboot，再嘗試：
