If that is what you are looking for I can help you. Not sure if this a limitation of using H. h264 and the video should play. 264 encoding happens at the camera module level and not in the software running on the RPi. The BCM2711 also has the "legacy" hardware codecs such as H. The default encoder used by libcamera-vid is the H. On Bullseye 64 bit with Raspberry Pi OS supplied ffmpeg/ffplay that command works fine for me and is definitely using hardware video decode. In the past with the buster image, I used ffmpeg to stream h264 video using the RPi hardware accelerated h264 encoder. RPi5 drops H264 hardware decode: which removes the 1080p cap There are two ways to use the hardware codec - either by using the newer h264_v4l2m2m or the h264_omx OMX based one.
