A. Screen settings

     My screen setting is HDMI, 1920x1080, the u-boot settings are:

          set hdmi_1080 'video=mxcdi0fb:RGB24,1920x1080MR-16@60 hdmi di0_primary'
          set bootargs_base 'setenv bootargs console=ttymxc0,115200 hdmi_1080'


B. Test video file of mpeg2 video :,  enter the folder i.MX/test_video, 908001.vob, 908002.vob


C. Test environment :

     a. lucid image from L2.6.35_11.01.00_ER_images_MX5X.tar.gz, rootfs.tar.bz2

     b. linux kernel 2.6.35 built from LTIB L2.6.35_11.01.00_ER_source_bundle

     c. linux kernel 2.6.35 built from LTIB L2.6.35_11.09.01_ER_source_bundle.tar.gz


D. Test procedure :

     gplay [test video filename]


E. Test result :

     a. (lucid image) : The video files can be playback, however, the screen will turn to black sometime with IPU error message prompted. After a few seconds, the video will appear on screen again.

          mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x00080000


     b. & c. (built from ltib) : The video files can not be playback normally, with VDI split not support message, and the frame rate only has fps:8, no video on screen at all.

          video4linux video16: VDI split has not supported yet.
          [Playing  ][Vol=01][00:00:01/00:02:53][fps:8]


Is there anybody know how to let these video play normally without screen turn to black ? Thanks.
