Start an upload

Returns the generated media_id plus a presigned PUT URL. Upload the raw bytes to upload_url with the same Content-Type you declared here, then call POST /transcriptions with the media_id to start the job.

Both video and audio files are accepted, so an audio-only podcast never has to be wrapped in a video container. The ceiling is the smaller of your plan's upload limit and the storage quota you still have free; FILE_TOO_LARGE reports the effective ceiling in max_size and STORAGE_LIMIT_EXCEEDED means the quota is full.
