Method and system for streaming a media file during a concurrent transcoding thereof

A server for streaming a media file for playback on a media player during a concurrent transcoding thereof, the server comprising:

• a memory;
• and
• a processor configured to receive from a client terminal a request for streaming a media file, wherein the request is sent responsive to a user request to playback a media file on a media player operating on the client terminal, and wherein the media file is coded with a first coding format that is not supported by the media player, to retrieve the media file, to transcode the media file from the first coding format to a transcoded media file in a second coding format that is supported by the media player, and to stream the transcoded media file over a communication network to the media player concurrently during transcoding, which comprises steps of:
• (a) reading metadata of the media file to retrieve media file duration and bit rate and calculating a total length of the transcoded media file;
• (b) determining a size of remaining transcoded media file as the total length of the transcoded media file and a size of a transcoded data fragment according to a bit rate of the media file;
• (c) transcoding a data chunk from a plurality of data chunks related to the media file from the first coding format respectively to a transcoded data fragment in the second coding format with a start position and an end position for positioning the transcoded data fragment in the transcoded media file relative to a beginning of the transcoded media file;
• (d) reducing the calculated size of the transcoded data fragment from the size of remaining transcoded media file;
• (e) sending the transcoded data fragment over the communication network for stream viewing on the media player while transcoding a next data chunk from said plurality of data chunks;
• (f) writing the transcoded data fragment into the transcoded media file in accordance with the start position and the end position relative to the beginning of the transcoded media file;
• and
• (g) repeating step (c) to step (f) until the size of remaining transcoded media file equals zero and all data chunks from said plurality of data chunks are transcoded to the second coding format and all respective transcoded data fragments are consecutively written into the transcoded media file;
• and
• storing the transcoded media file in a memory.
