7. The method of claim 2 , further including exchanging messages with a video player to pause or cancel transcoding responsive to directions from the video player.
8. The method of claim 2 , further including identifying the format compatible for video streaming to the particular mobile device and automatically adjusting transcoding parameters to match the particular mobile device.
9. A computer readable storage medium including program instructions that, when executed, configure a processor to perform actions including:
receiving an ad availability record, compatible with a video ad serving template standard, with a source URL for video ad content that is in a format incompatible with a device that is requesting ad content;
allocating a URL from which to stream the requested ad content;
responding to the request for the ad content by:
sending at least the allocated URL and some information from the ad availability record to the requesting device;
identifying a change in the format for video streaming being used by a particular mobile device and automatically adjusting transcoding parameters to match; and
automatically transcoding the ad content to a live video stream accessible at the allocated URL in a format compatible with the requesting device.
