GDR activation in 365

Hello

 

Is anyone knows if activating GDR function at this platform (365) has any limitations ?

I mean when working at bits/slice mode it should work fine ? or it works only with MB/Slice mode ?

When activating GDR both with Enable_GDR=1 & Enable_GDR=2, the image is courrpted and there are

image artifacts .After few minutes the image is freezing totaly .

 

Other issue Multiple slice = ON has affects too ?

Regards

Gidi

    Hi Gidi,

    Please share your encoder version(hope you are using latest version, if not pleass upgrade), all encoder parameters and encoded video stream.

    GDR should work with every mode. During GDR duration sliceMode and sliceSize params will get overriede. sliceMode change to sliceMode = 3(MB Rows /slice) and sliceSize  will be calculated depending upon GDRduration and video height parameters. Once GDR Duration will complete sliceMode and sliceSize will reload with original values.

    Depending upon input sequence you should set  EnableGDR = 1 or 2.  For most of the sequences EnableGDR = 1 works well. And if your input is static  video and very low bitrate, EnableGDR = 2 will works well.

    Setting multiple slices also should work fine.

     

    Thanks,

    Hi,

    One more possible way in application to handle H241 during GDR duration is packetizing the NAL unit as fragmented NAL units. There are some techniques like FU-A are available for the same.

     

    Thanks,
