The VIN Gen3 hardware don't have Line Post-Clip capabilities as VIN Gen2 hardware have. To protect against writing outside the capture window enable field toggle after a set number of lines have been captured. Capturing outside the allocated capture buffer where observed on R-Car Gen3 Salvator-XS H3 from the CVBS input if the standard is misconfigured. That is if a PAL source is connected to the system but the adv748x standard is set to NTSC. In this case the format reported by the adv748x is 720x480 and that is what is used for the media pipeline. The PAL source generates frames in the format of 720x576 and the field is not toggled until the VSYNC is detected and at that time data have already been written outside the allocated capture buffer. With this change the capture in the situation described above results in garbage frames but that is far better then writing outside the capture buffer.
