H264 decoder long delay

Hi,

I'm decoding H264 video stream on DM6467t using h2641080p60vdec (ver. 1.20.00.14) or h264dec (ver. 01.10.04.00) decoders. Sometimes, every few minutes, the call to decoder's Vdec2_process takes very long - about 1 sec. The input encoded stream is 720P60 created with h264fhdvenc 01.10.02.03 encoder.

Please help me solve this problem.

Thanks.

6467t

    What version of DSP Link are you using?

    If not the latest, you might try updating - my recollection is that there was a rare issue like that 1 sec delay in some earlier releases, but it was fixed a year or two ago.

    Hi Chris,

    Thank you. I have updated the dsplink_linux from 1_64 to 1_65_01_06, and the delays reduced to ~70ms.
