DM6467 H264 Decode problem

Hi，

My project ： Getting two channel H264 IP stream from ethernet，and using Ti h264dec to decode them， then encoding them with ittiam h264hdenc .

The problem ：when I execute it， a few minutes later， the DSP is not running any more。before this phenomenon happens， our h264dec should printf IVIDDEC2_Status.extendError = 2118 or 2625 or 2630 several times。

So，can U give me some advice ？

    Hi,

    These error are related to corrupted bitstream. Do you expect any error in input bitstream of decoder? If not please check it. Or else if you are expecting an error, by seeing error code it looks fatal error bit is getting set. So please have look at userguide for fatal error handling.

    If the fatal error bit is set, that means the decoder has encountered a non-recoverable error. In this case you need to re-set the decoder again.

    For non-fatal errors, the decoder will recover on its own. It might so happen that during recovery some frames are corrupted, the decoder will signal this back to the application via outargs.

    Regards
