<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">For my initial pass, I only looked at the .h files (with the exception of vector.h) and made comments based on questions I'd have as a user of the API based on the documentation provided. I imagine that my next pass, which will be looking at the .c files, will answer some of my questions. I figure that posting these can help to solidify the API documentation though and lets people avoid having to look at the implementation to figure out what's going on.
As far as usability of the API is concerned, it seems pretty similar to the old format APIs, so adjusting wouldn't be too difficult. Probably the biggest difference is the immutability requirements on ast_format structures. That may need some further explanation, like what is specifically unsafe to do with an "immutable" format.</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;">So since we're in the early stages of this, I'm going to request that documentation for these fields be more specific.
sample_rate: What are the units for this? Is this samples per second or something else?
minimum_ms and maximum_ms: Is this the maximum number of milliseconds per sample or for some other time slice?
increment_ms: I'm completely in the dark on what this means just from the description. The length of what, exactly? Under what circumstances are we talking about increasing the number of milliseconds of something?
default_ms: When you say "length of media" is that the length per sample?</pre>

When you say "same format type", does that mean that format1 and format2 have to be the same format type? And what does "same format type" mean? Does it mean that both formats are audio formats, or is it more specific than that?
Also, there's red here.</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;">This change has a few things in it:
1. Some media related things have been moved around to more logical places or their own parts (smoothers).
2. A new implementation of media formats according to https://wiki.asterisk.org/wiki/display/AST/Media+Format+Rewrite. The implementation doesn't completely adhere to the design since I tweaked things but it mostly conforms.
3. Unit tests for the above implementation.
What I'd like feedback on is the actual media formats implementation and the API design itself. Is this something you would be comfortable using?</pre>

Note: I know AO2 throws a fit and it's because a container isn't getting initialized. Getting said container initialized requires beginning the hacking apart process.</pre>
