miss: unsupported vendor

Error message

miss: unsupported vendor %s

What it means

NewClient read the 'vendor' query parameter from the xiaomi:// URL and it is neither 'cs2' nor 'tutk', the only supported transports. The connection is never dialed; the offending vendor string is included.

Solutions

1. Set vendor=cs2 or vendor=tutk in the connection URL query
2. Fix typos/case in the vendor value
3. Check the miss package docs for the exact accepted vendor strings
4. Use the correct transport for your hardware (cs2 for CS2-based, tutk for TUTK-based cameras)

Example fix

// before
u := "miss://host?vendor=csj&uid=..."
// after
u := "miss://host?vendor=cs2&uid=..."

vendor := u.Query().Get("vendor")
if vendor != "cs2" && vendor != "tutk" {
    return fmt.Errorf("vendor must be cs2 or tutk, got %q", vendor)
}

When it happens

Trigger: Calling Dial with a miss:// URL whose vendor query parameter is missing or not one of 'cs2' or 'tutk'.

Common situations: Missing vendor= query parameter in the connection URL; typo such as vendor=CS2 (case mismatch) or vendor=tutk2; copying a URL pattern from a different camera family.
