[FFmpeg-devel] [PATCH 1/1] This change adds an encoder for Camera metadata motion. This is a type of sensor data associated with video, such as GPS, acceleration, gyro, and camera orientation. It does not encode video itself, but rather, this metadata.

That file had unrelated changes that shouldn't have been there, please
ignore them.
Now that there is no codec associated with the stream, there shouldn't be a
codec tag at all, I would assume. (Another issue I need to deal with is
that the MOV muxer also doesn't support streams without a codec, but that
is separate.)
