DM365 : MPEG-2 encoder issue

Kanae
Guru 10165 points


Hi.
I would like to know about MPEG-2 encoder on the following status.
My questions are the reason and the workaround to this issue.

-Issue: MPEG-2 encode has stopped after a few minutes.
-EVM: DM365
-MPEG-2 Encoder: 01.00.00.07
-DVSDK: 2.10.01.18

    Hi,

    Did you modify anything in DVSDK?

    Are you able to run other encoders?

    Hi, Neelakanth.
    Thank you for your concerning with my question.

    Did you modify anything in DVSDK?
    >>> No.
    Are you able to run other encoders?
    >>>No.

    I also would like to make sure about "IMP2VENC_DynamicParams".
    Do you know the actual performance or result of "IMP2VENC_DynamicParams"?
    If you know how it works, please let me know the details.

    Regars,

    Hi,

    Can you try running other encoders? Demos from the DVSDK should be able to run out of box. If demos are not running out of box then I will ask concerned team to look into it.

    About the dynamic params (IMPEG2VENC_DynamicParams): Some of the params affect the performance. For ex: reset_vIMCOP_every_frame, when set to 1, it will reduce the performance because at start of every encode code will be loaded into HDVICP memory.

    Hi.
    JPEG encoder is OK, but others were not checked yet.
    reset_vIMCOP_every_frame sets to 0 because when it set to 1, 
    the encoder     will reduce the performance as you mentioned.
    I hope you will ask concered team to look into this issue.

    Kanae,

    Sorry for not being clear in my previous answer. Can you run h.264 or mpeg4 encoders? if these application does not work then I will ask concerned team to look into it.

    When reset_vIMCOP_every_frame is set to 1, the performance will get reduced. This reduction is not significant. What is the perormance you are looking for?
