This patch introduces udev rules to ensure consistent device naming for VPU decoders, encoders, and the JPEG encoder. These rules are essential for enabling hardware-accelerated video decoding in Chromium using the V4L2 Stateful decoder. The following udev rules are added: - Map vpu and vpu0 to /dev/video-dec0 and /dev/video-enc0. - Map vpu1 to /dev/video-dec1 and /dev/video-enc1. - Map the JPEG encoder to /dev/jpeg-enc0. These changes ensure proper operation of the VPU and JPEG encoder, especially when other video devices are connected, avoiding mismatches.
