TDA4VM: How to modify Encode to support 2560x1920 resolution video coding?

Part Number: TDA4VM
Other Parts Discussed in Thread: TDA2

Hi TI,

Is there any way to configure Encode to support the encoding of 2560x1920 resolution video? (We've implemented it on TDA2)

According to the user guaid of Encode, the upper limit of the resolution supported by Encode is 2048x2048. 

Could you please give me some advice on how to expand this restriction?

Thanks & Regards

Damon

    Hi Damon,

    which sdk release are you using? 

    As far as i remember, the max resolution tested is 1080p (1920x1080).. Beyond this resolution, it is not validated..

    Regards,

    Hi Brijesh,

    My sdk is 07_03. 

    I'm sorry I was wrong about the max resolution stated in user guaid。 It is indeed 1920x1080

    However, according to the log error message and the settings in the code, it seems that the max resolution is 2048x2048(this may be the case of low frame rate?)

    But what I am most concerned about is whether we can make Encode support 2560x1920 through some special modification? Although it may be necessary to sacrifice a little frame rate.

    Regards,

    Damon

    Hi Damon,

    As i said, we have not really tested more than 1920 frame width. This may also changes in the OpenVX/Vision_apps to provide memory, in addition to encoder support..

    Hi,

    On latest SDK 07_ 03_ 00_ 07, it is tested for resolutions upto 1920x1080.

    There is an example standalone test-application inside SDK (ti-processor-sdk-rtos-j721e-evm-07_03_00_07/video_codec/examples/apps/encoder/app_encoder_test.c) You can refer to code with macro "TWO_SLICE_ENCODING". That might help you try encoder higher resolutions with multi slice enabled. You can try adapting those changes in your use case.

    Again, only the multi slice functionality was validated here and not the higher resolutions beyond 1920x1080.
