Abstract
A bitstream encoding or decoding job is broken up into a plurality of segments, each of which is independent from subsequent segments and corresponds to a respective fence identifier. The segments are individually processed and progress is indicated using the fence identifiers. In some cases, a first segment is encoded, transmitted, decoded, and processed before a second segment is encoded. As a result, in some cases, segment statuses are more easily tracked, hardware is used more efficiently, end-to-end processing time is reduced, and less communication network bandwidth is used.
Claims20
A method comprising:
- receiving a bitstream encoding job to send an encoded version of bitstream data to a consumer as a bitstream;
- and
- in response to encoding a first segment of the bitstream data based on the first segment being independent from other segments of the bitstream data, but prior to completing encoding of the bitstream data:
- indicating, using a first fence identifier, that the first segment has been encoded;
- and
- writing the encoded first segment to an output buffer.
A system, comprising:
- at least one processor;
- and
- a non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate the at least one processor to:
- receive a bitstream encoding job to send an encoded version of bitstream data to a consumer as a bitstream;
- and
- in response to encoding a first segment of the bitstream data based on the first segment being independent from other segments of the bitstream data, but prior to completing encoding of the bitstream data:
- indicate, using a first fence identifier, that the first segment has been encoded;
- and
- write the encoded first segment to an output buffer.
A method, comprising:
- receiving, at a producer, a bitstream encoding job to send an encoded version of bitstream data to a consumer as a bitstream;
- in response to encoding a first segment of the bitstream data based on the first segment being independent from other portions of the bitstream data, but prior to completing encoding of the bitstream data:
- indicating, using a first fence identifier, that the first segment has been encoded;
- and
- sending the encoded first segment to a consumer as part of the bitstream;
- receiving, at the consumer, the encoded first segment as part of the bitstream;
- and
- in response to decoding the encoded first segment but prior to completing decoding of the bitstream, indicating, using the first fence identifier, that the encoded first segment has been decoded.
