pipewiresrc V4L2_PIX_FMT_JPEG negotiation fails
Created by: mfend-wv
I struggled to get a pipewiresrc running together with a v4l2 capture device when V4L2_PIX_FMT_JPEG is reported as pixel format. During debugging I found out that the setup is working if the v4l2 device reports V4L2_PIX_FMT_MJPEG instead. Is there a specific reason that 'image/jpeg' is mapped to 'media_subtype_video.mjpg' (vs. 'video/x-jpeg', 'media_subtype_video.jpeg').
