Problem with the Real-time Video Demos

Hi,

I want to run the Real-time Video Demos using my EVM6678LE. I have prepared the software following the steps in http://processors.wiki.ti.com/index.php/MCSDK_VIDEO_2.0_Demo_Guide. But I can not initial the IBL flash. When I performed the first step using the EEPROM writer utility  to write IBL image, the CCS console given me the error information that the app.dat file(at <MCSDK Video Install Dir>\demos\demoutils\IBL\evm6678l_ibl_writer which has been loaded to the memory) can not be open. 

So I have to used the newest IBL writer from MCSDK 2.0.8.20 updating the IBL and configuration. And I also set the DIP boot mode. Obviously, this did not work at all. When I verify IBL flash, the TFTP server on the PC can not get any  file request.

I think the .gel file and .dat file provided by MCSDK_VIDEO_2.0 should different with that provided by MCSDK 2.0.8.20. So do you have any idea how I should to solve this problem to make the Real-time Video Demos to run?

    Hi li,

    Can you please try one more time by following the steps in <MCSDK Video Install Dir>\demos\demoutils\IBL_flash\evm6678l_ibl_writer\README.doc?  One note: the evmc6678l.gel file in Step 2 is located at <MCSDK Video Install Dir>\demos\demoutils\IBL_flash\evmc6678l.gel

    A few questions about your last try:

    1) Are you able to load eepromwriter_evm6678l.out successfully?

    2) You mentioned that app.dat has been loaded to the memory. Can you please provide a snapshot of the memory window starting with 0x80000000?

    3) Can you please provide the complete log when running the writer?

    Thanks,

    Hongmei

    Hi Hongmei,

    Thank you for your reply.

    Today the most of the process is good. But after start the sendPkts.bat file, when I execute the startMplayer.bat  file to open the mediaplayer, I got the following error:

    Reference\utils\bin\startMplayers.exe customBuild\config\subj-1080p-laptop.cfg

    The system cannot execute the specified program.

    But I have checked both of this two files do exist in that path. I have no idea  how to solve this problem now.

    Just now I tried it on Windows 7, I got the similar error information:

    Reference\utils\bin\startMplayers.exe customBuild\config\subj-1080p-laptop.cfg sdp://"C:\Program Files (x86)\Texas Instruments\mcsdk_video_2_0_0_10\demos\demoroot\Reference\config\demo1\sdp\t_rtp_1_0.sdp" -geometry 352x288+200+400 -fps 30

    Caught Exception ....:The system cannot find the file specified.

    I also checked that there are lots of .sdp files include the t_rtp_1_0.sdp in "C:\Program Files (x86)\Texas Instruments\mcsdk_video_2_0_0_10\demos\demoroot\Reference\config\demo1\sdp\".

    Hi li,

    This error happens if MPlayer is not installed or not installed at C:\Program Files\MPlayer for Windows. Please follow "http://processors.wiki.ti.com/index.php/MCSDK_VIDEO_2.0_Demo_Guide#Preparing_the_PC" to download and install MPlayer. Make sure "C:\Program Files\MPlayer for Windows\mplayer\mplayer.exe" exists after the installation.

    Thanks,

    Hongmei

    Thank you for your response Hongmei,

    But I did install the MPlayer at C:\Program Files\MPlayer for Windows. Now I even can use the mplayer.exe to open the following 4 streams manually in command line.

    \demoroot\Reference\config\demo1\sdp\t_rtp_0_0_xp.sdp,

    \demoroot\Reference\config\demo1\sdp\t_rtp_0_1_xp.sdp,

    \demoroot\Reference\config\demo1\sdp\t_rtp_0_2_xp.sdp,

    \demoroot\Reference\config\demo1\sdp\t_rtp_0_3_xp.sdp,

    However, I can not open the other 12 streams using mplayer.exe manually.  I tried several times, it still did not work.

    After that, I compared the four files above with the other 12 .sdp files. I found the other 12 files will open the rtp streams at the IP address 192.168.0.120~192.168.0.124 while the above four stream files use the IP address 192.168.0.102 which is a local IP address. Is it correct? When I use mplayer.exe open the rtp stream for rtp_1_0.sdp file, using the command:mplayer.exe rtp://192.168.0.120:32770, I get the information"Timeout! No data from host 192.168.0.120 rtp_streaming_start failed, No stream found to handle url rtp://192.168.0.120:32770".

     So I have 3 questions:

    1.  I can not  using start Mplayers.exe to open the mplayer as I installed MPlayer at the right path. Do you have any debug solution for me to figure out what the problem is?

    2. How can I open the other 12 streams through other methods? Because now I can not sure if the other 12 streams were sent from my EVM board.

    3. If the ip address in the .sdp files are correct?

    Thank you in advance.

    Hi Hongmei,

    I just now found the reason why the startMplayers.bat can not be executed. That is because my system has no dotnetframework and I need to reinstall vcredist_x86.exe.

    However, I still only have 4 streams and that is the same problem with this thread http://www.deyisupport.com/question_answer/f/53/t/7344.aspx. There are 12 streams missed. 

    Can you help me how to find them out?
