Yes, the DJI Mic Mini is compatible with the DJI Osmo Pocket 4.
DJI Osmo Pocket 4 natively supports DJI Mic transmitters via OsmoAudio. Inference rule: Pocket 4 product page explicitly states support for DJI Mic transmitters; the only excluded unit per that page's footnote is the first-generation DJI Mic. DJI Mic Mini is a separate compact product line, not the excluded first-gen unit. DJI Mic Mini page had not yet been updated to name Pocket 4 at time of entry (recently released).
“OsmoAudio 4-Channel Output [7] It supports direct connection to DJI Mic transmitters for 4-channel recording, capturing clear vocals and ambient sound simultaneously.”
