From 8865c537037bb30b9e84c91e3386cc926f024f78 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Fri, 18 Jun 2021 14:29:14 +0200 Subject: media: uvcvideo: Increase the size of UVC_METADATA_BUF_SIZE Hans has discovered that in his test device, for the H264 format bytesused goes up to about 570, for YUYV it will actually go up to a bit over 5000 bytes, and for MJPG up to about 2706 bytes. We should also, according to V4L2_META_FMT_UVC docs, drop headers when the buffer is full.
