Memory management for video decoding

One or more tangible computer-readable media storing computer-executable instructions for causing a computing system programmed thereby to perform video decoding operations comprising:

• receiving at least part of a bitstream for a video clip, wherein the video clip includes at least one picture encoded using at least some inter-picture coding;
• determining first memory usage settings for decoding intra-coded content of the at least one picture;
• determining second memory usage settings for decoding inter-coded content of the at least one picture;
• and
• decoding the video clip, including adapting memory usage based at least in part on the first memory usage settings and the second memory usage settings.

A computer system comprising:

• a buffer configured to store at least part of a bitstream for a video clip, wherein the video clip includes at least one picture encoded using at least some inter-picture coding;
• a video decoder configured to:
• determine first memory usage settings for decoding intra-coded content of the at least one picture;
• determine second memory usage settings for decoding inter-coded content of the at least one picture;
• and
• decode the video clip, wherein the video decoder is configured to adapt memory usage based at least in part on the first memory usage settings and the second memory usage settings.

In a computer system that implements a video decoder, a method comprising:

• receiving at least part of a bitstream for a video clip, wherein the video clip includes at least one picture encoded using at least some inter-picture coding;
• determining first memory usage settings for decoding intra-coded content of the at least one picture;
• determining second memory usage settings for decoding inter-coded content of the at least one picture;
• and
• decoding the video clip, including adapting memory usage based at least in part on the first memory usage settings and the second memory usage settings.
