<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A bit ugly... since this function has no ability to 'fail', this has to be absorbed. This should only occur under extreme memory pressure conditions, though, so the resulting unusual behavior (missing one or more default format/payload items) will probably be lost in the noise. It would probably be worth adding a comment here to indicate why the memory allocation failure is not fatal, though.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It is safe to have the same 'struct ast_rtp_payload_type' instance be linked into multiple containers? Semantically this seems risky, as changes in the object in the source container would affect the destination container too.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">While doing the media attribute work I needed to increase the available space for attribute information but this has caused stack space usage to increase. While I have reduced it some there is still quite a bit of memory being consumed. To help with this I have converted ast_rtp_codecs to use astobj2 internally for storing payload information. The only memory used will be that of payloads present in the structure, and not a huge array containing every possible one. For all cases this should reduce memory consumption considerably and for most cases should reduce it to an amount lower than before attribute support was even added.</pre>
