Can't run the qtdemoE when the vs2 demo running

hi all,

      1. after linux bootup I run the qtdemoE in the /usr/bin/ ,  like this

       qtdemoE -qws &

       and qt gui shows, and then I run the vs2 demo,   the qt gui disapear, what the problem is ?

       Are xx_m3vpss.xem3 and the ti81xx_hdvpss.xem3 in conflict ?  

        2. I find ti81xx_hdvpss.xem3 loaded by fireware_loader in /etc/init.d/load_fireware.sh

        if I stop load_fireware, the /dev/fb* will disapear, and modproe ti81xxfb, but /dev/fb* will not be ceate!

        3. I use the EZSDK is 05000009

so, how to run the qt gui and vs2 demo simultaneously?

thanks and regards

Qin Yang

  • Qin,

          As you pointed out the M3 firmware binaries used by FbDev & VS2 are different. IN your experiment you acutall load ti81xx_hdvpss.xem3 when running FbDev (which does not support VS2) & loading xx_m3vpss.xem3 firmware when running VS2 (Which does not support FbDev)

         so the other applicaiton or the entire system will crash if mix & match is done here.

         To really support FbDev & VS running simultaneously single combined firmware needs to be created with both the support. This feature is not present in 05000009. This feature will be supported in upcomming release.

  • hi Velan,

               Thank you so much for your reply!  When the upcomming release is  available?

              1.  I just want to decode one or severals  1080p h.264 HD streams and display, no need the TVP capture. how to do that  ?

               I learn the vs2 demo to create a chain      dmux   ->   vfpc_sw  ->  vfdc,  and run it but failed. It looks so complicated and hard to use the vs2 demo.

              If you can give me some examples will be very helpful.

    Thanks and Regards!

  • Hi Velan,

                I have a problem about how to decode a mpeg4 stream from dm355 ip camera, in the ezsdk0500009 found no mpeg4 codec intergrated, and the stream of new ip camera dm368 is h.264.  How to decode mpeg4 and h.264 compatibility?

    thanks and regards,

  • Qin,
