Abstract
In various embodiments, video streams are decoded using decoders that support a different decoding profile. First processing circuitry is configured to receive a video stream encoded using a first encoding profile, transcode the video stream from the first encoding profile to a second encoding profile, and store the transcoded video stream in an output buffer. Second processing circuitry is configured to receive the transcoded video stream from the output buffer and decode the transcoded video stream according to the second encoding profile. The second processing circuitry may be unable to decode the video stream encoded using the first encoding profile.
Claims20
A system, comprising:
- first processing circuitry configured to:
- receive a video stream encoded using a first encoding profile;
- transcode the video stream from the first encoding profile to a second encoding profile;
- and
- store the transcoded video stream in an output buffer;
- second processing circuitry configured to:
- receive the transcoded video stream from the output buffer;
- and
- decode the transcoded video stream according to the second encoding profile;
- and
- wherein the first encoding profile is unsupported by the second processing circuitry.
A system, comprising;
- first processing circuitry configured to:
- receive a video stream encoded using a first encoding profile;
- transcode the video stream from the first encoding profile to a second encoding profile, wherein the second encoding profile employs a same header format as the first encoding profile;
- and
- store the transcoded video stream in an output buffer;
- second processing circuitry configured to:
- receive the transcoded video stream from the output buffer;
- and
- decode the transcoded video stream according to the second encoding profile;
- and
- wherein the second processing circuitry is unable to decode the video stream encoded using the first encoding profile.
A method, comprising:
- receiving, by first processing circuitry of a video processing device, a video stream encoded according to a first encoding profile;
- transcoding, by the first processing circuitry, the video stream from the first encoding profile to a second encoding profile;
- providing, by the first processing circuitry, the transcoded video stream to an output buffer;
- receiving, by second processing circuitry of the video processing device, the transcoded video stream from the output buffer;
- and
- decoding, by the second processing circuitry, the transcoded video stream, the first encoding profile being unsupported by the second processing circuitry.
