Give the standard not compliant video sample a chance if its size in the mp4 header is invalid

            uint16_t width = U16_AT(&buffer[6 + 18]);

            uint16_t height = U16_AT(&buffer[6 + 20]);

            // The video sample is not stand-compliant if it has invalid dimension.

            // Use some default width and height value, and

            // let the decoder figure out the actual width and height (and thus

            // be prepared for INFO_FOMRAT_CHANGED event).

            if (width == 0)  width  = 352;

            if (height == 0) height = 288;

            // printf("*** coding='%s' width=%d height=%d\n",

            //        chunk, width, height);
