Dear Jack,

I also have the requirement for dual display. But have problems to work. My problems had posted to http://imxcommunity.org/forum/topics/i-mx53-qsb-dual-monitor-setup-problem-with-lucid. But nobody reply me yet.

Can you share your working settings ? What's your display resolution for each display ? What's parameters in UBOOT ?

It's strange that I can not use mfw_isink, the error message is "can not create threadmfw_gst_isink_setcaps:1080", do you have any suggestion ?

thanks for your reply and help!

finally,  I can use MX53 decode multiple video and display on different screen or display on the same screen simultaneously

the mfw_isink plugin is powerful.

i have test that MX53 QSB can decode two 720p video at the same time, however, when I try to play the third video, it occur error about the mem page !

So, I want to know if I add more mem into the board, Can it play more HD video?

thanks advance！

Use gstreamer plugins support multi video playback.

Yes the i.MX53 is able to handle this. I would split the restrictions in three parts: dual display size, video processing (resize) and video decoding. - Dual Display size: See pptx document, there you could check the combinations that i.MX53 supports. - Resize: Sometimes the size of the video does not match with the screen size or maybe the user is able to resize the video. In those cases we need to resize the video before send it to the screen. Resize is handled by one IPU module, the Image Converter(IC). Unfortunately this module has some bandwidth restrictions, so it won't be recommendable to use the IC for both video paths because the frame rate might be affected. The bandwidth will be also shared between decoding operations if they need to be resized. IC might be also shared with other tasks such video or camera capture when resize is required. Anyway IC's bandwidth is: - Image converter Input Rate 150 Mpixels/sec (e.g.,4 MP @ 30 fps + 35% blanking intervals) - Image converter output rate to system memory 75 Mpixels/sec
