Default structure for translators, with the basic fields and buffers, all allocated as part of the same chunk of memory. The buffer is preceded by AST_FRIENDLY_OFFSET bytes in front of the user portion. 'buf' points right after this space.

struct ast_format* explicit_dst |
If a translation path using a format with attributes requires the output to be a specific set of attributes, this variable will be set describing those attributes to the translator. Otherwise, the translator must choose a set of format attributes for the destination that preserves the quality of the audio in the best way possible. For example with the Opus Codec, explicit_dst contains an attribute which describes whether both parties want to do forward-error correction (FEC).
