VLClib error: ES_OUT_RESET_PCR

Question

I used VLClib in my C# code to play a RTSP Stream. and OpenCV in C++ for some processes on this stream's frames. in Output window, I got this messages:

core input error: ES_OUT_SET_(GROUP_)PCR  is called too late (pts_delay increased to 300 ms)
core input error: ES_OUT_RESET_PCR called

And after that, every time I have some problem like Attempted to read or write protected memory on exactly the line that called my OpenCV code. which I don't know if they related to this messages or not.

But anyway, what is the meaning and cause of these messages? I searched, but most of the result was about VLC player and its problem with DVDs.

this is my whole logs:

Solution

Those messages come from the access module of VLC where it is complaining about corruptions in your stream. If you were playing local content, this would be an indications that your files are bad. For streaming content, this is pretty normal especially when using WiFi as packets can get lost. It is generally save to ignore those errors.

The video display errors are from the video output core, since you are deploying a video output module which does not said features, which again, is absolutely non-problematic. Those errors are provided so you are not surprised that certain features won't work.
