how to modify the OMTB script for two 1080P60 H264 compression

Other Parts Discussed in Thread: TVP7002

HI , TI engineer

    I want to use TMDXEVM8168 to compress two chanle 1080P60 in H264 and save them into file.

I want to use two instance of h264venc , two instance of vfcc , and two instance of dei ,but when I

convert h264venc to IDLE state,it is block.

   The version of sdk I used is 5_01_01_80,is two 1080p60 compressed supported in this version or any other problem?

Thank you.

  • Hi,

    First I would advise to take the latest SDK 5.03.1.15 (avilable over net). We have encode file I/O exampel in the same, you could try that. Other than that, For using two VFCC, you have to program two VIPs of DM8168. EIO board with the EVM is suppoting only component capture only, so two captures can not be done on EIO board.

  • Thanks for your answer

        I only want to capture two chanle component video.

    DM8168 have two VIPs(16bit and 24bit) with two TVP7002.I just feed them with two YPbPr.

    I have finished one chanle but I fialed on the onther chanle.

    how can I modify the script for two chanle capture ,dei and h264venc?

  • I assume you have EIO card with the EVM. we support only one capture on this board, so other capture is not possible on this boad.

  • I have Expansion I/O daughtercard.

    If I have this card ,I only capture one chanle? but I have seen wo TVP7002 on the EIO,and they connect to the VIP of DM8168.

    I just want the same two chanle with YPbPr format on EVM and EIO,is it permitted?

     

  • Board has the HW to support two capture, however we do not have driver for enabling the same. That's reason we can not have two capture on this board.

  • That is to say I have no way to capture two 1080P60 chanle?

    I  want to design like this :

    two 1080P60 captire --> two dei --> two H264venc  --> PCIE transmit to PC(or save to file)

    is there any way to make it come true?

     

    Thanks

  • Unfortunately, we can not have two captures. Other than capture, it is possible to have other components for two 1080p60. If I come across possibility of two capture on this board, i will post to you.

  • Will the two capture driver for two component video be provied in the next version of EZSDK?

    If it is ,when we could get this version?

    By the way ,is two h264venc driver provied in the lasted version? or can I make two instances of h264vnec in the OMTB script ?

    Thanks

     

  • Currently it is not planned for dual capture on that board.

    Other than capture encode/ decode/dei/display can be opened / create twice.

  •     Thanks for your help

        I also have some question.

        If I use DM8168 to design a compress system,I only can design one chanle 1080P60 for H264 compression because of no driver ,yes or no?

        Is there any way to use two VIP simultaneously?

  • Dual Capture is possible on VC daughter card. This card can be used along with Base Card. ( You have base card + EIO card). Please check with local TI contact to arrange for VC daughter card. DM8168 has been used on other boards for dual capture.

    Regards

  •     I cannot undestand what you said.

        You have said that there is no driver for two chanle capture,but you also said that base card can capture dual chanle 

         ( DM8168 has been used on other boards for dual capture)

        I want to design my board for two 1080P60 capture,two dei and two h263vnec and then pass them to PC through PCIE based on DM8168,I want to know whether it can be      achieved  by current EZSDK.

        Now ,we are designing HW like this ,the question for me  is very important,please give me a detail answer ,thank you.

     

       

  • Lemon,

    What I meant is we do not have drivers on EIO board, so we can not run dual capture on that board. device DM8168 supports dual capture, but the board in which this device has been put should have working interface for dual capture. Some members have their own board where they have dual capture interface, so they can run dual capture. VC board from TI also support dual capture.

  • HI AE:

        I have my own board for DM8168 which can be feed by FPGA through VIP.

    Now , I can feed the vip of dm8168 with two channel,

    1)    can I use the lasted OMX to do this described below?

    2)   how can I modified the demo (capture_encode) to finish this ?

    I want to do :

    2 capture(1080P) -> 2 DEI -> 2 encode(h264) -> PCIE to PC
