Hi,

Can you elaborate your question?
You can not select frames at run time.
You can connect ccs and work on an specific frame.

I want to collect data in the automobile, in which the video frame is collected based on the current distance of the vehicle, such as per 0.5 meters to collect a video frame. Can I do this in TDA2XX?

Others: Is there an algorithm to select the video frame I want? Such as Alg_FrameCopy, can it do this?

HI,

Alg_FrameCopy will just copy the frame to a different buffer.
There needs to be a link which will detect the distance ob an object.

I designed such a chain like this:

NullSource (A15) -> Decode -> Dup_dec

Dup_dec -> Alg_FrameCopy (A15) -> VPE -> Display

Dup_dec -> Encode -> Null (A15)

Void chains_nullSrc_frameCopy_Display_Null_SetFrameCopyAlgPrms(
    AlgorithmLink_FrameCopyCreateParams* pPrm,
    Chains_Ctrl* chainsCfg) {
    pPrm->baseClassCreate.algId = ALGORITHM_LINK_A15_ALG_FRAMECOPY;

    pPrm->maxWidth    = ENCDEC_MAX_FRAME_WIDTH;
    pPrm->maxHeight   = ENCDEC_MAX_FRAME_HEIGHT;

    pPrm->numOutputFrames = 3;
}

input video h264 and dump video h264 is same，but display video displays like snowflakes. Why?

hi, Anuj Gupta:

I add a SgxFrmcpy link to solve this problem!

NullSource (A15) -> Decode -> VPE -> Alg_FrameCopy (A15) -> Dup_dec
Dup_dec -> SgxFrmcpy (A15) -> Display
Dup_dec -> Encode -> Null (A15)

Thanks!

Hi,

At run time how you want to select a frame .
You can use a select link which can select a channel of a link but not any particular frame.
If you want to select a frame then there needs to a link which can select depending upon your condition.
Currently we do not have any such link.

Anuj
