i have faced this similer error. tried many versions of ffmpeg

Any solution?

I had a similar error which was fixed when I realized that the code assumed that the VideoReaderState vr_state.sws_scaler_ctx was initialized to NULL. Since it is a local variable on the stack, it is not and the scaler was usuing a random part of memory as it's context. I added a constructor with initialization and my error was resolved. See commit d56d8c44136ae8d73770021c5424398796309ca7

If Bart wants a pull request, I can put one in. alternatively you can fix by adding after line 33 in main.cpp

VideoReaderState vr_state;
vr_state.sws_scaler_ctx = NULL;  // add this line as this pointer  is checked later to see if initialized and it must be NULL in order for initialization to happen
