How to deal with cv::VideoCapture decode errors?

I'm streaming H264 content from an IP camera using the VideoCapture from OpenCV (compiled with ffmpeg support).

So far things work ok, but every once in a while I get decoding errors (from ffmpeg I presume):

[h264 @ 0x103006400] mb_type 137 in I slice too large at 26 10
[h264 @ 0x103006400] error while decoding MB 26 10
[h264 @ 0x103006400] negative number of zero coeffs at 25 5
[h264 @ 0x103006400] error while decoding MB 25 5
[h264 @ 0x103006400] cbp too large (421) at 35 13
[h264 @ 0x103006400] error while decoding MB 35 13
[h264 @ 0x103006400] mb_type 121 in P slice too large at 20 3
[h264 @ 0x103006400] error decoding MB 20 3

These messages show up in the console. Is there any clean way to listen to these ? I'd like to skip processing the glitchy frames.

Any hints/tips ?

what sturkmen said is absolutely right, the opencv version is 2413, and for some reason, I can not update the opencv to 310, I know there is gonna be no any decoding error like this for opencv310. So firstly, I copy lib opencv_ffmpeg310_64.dll to my executable file path E:\GITHUB\JpegRtspCamera\vs2013\JpegRtspCamera\x64\Release

then I just delete opencv_ffmpeg2413.dll and change the name opencv_ffmpeg310_64.dll to opencv_ffmpeg2413.dll. it works!!!
