ff_aac_coder_init_mips() modifies a static const structure of function pointers. This will crash if the binary uses relro and is a data race in any case. Furthermore it points to a maintainability issue: The AACCoefficientsEncoder structures have been constified in commit fd9212f2edfe9b107c3c08ba2df5fd2cba5ab9e3, a Libav commit merged in 318778de9ebec276cb9dfc65509231ca56590d13. Libav did not have the MIPS-specific AAC code and so this was fine for them; yet FFmpeg had them, but this was not recognized. Commit 75a099fc734a4ee2b1347d0a3d8c53d883b95174 points to another maintainability issue: Contrary to ordinary DSP code, this code here is way more complex and needs to be constantly kept in sync with the ordinary code which it mimicks and replaces. Said commit is the only commit actually changing aaccoder.c in the last few years and the same change has not been performed for the MIPS clone; before that, it even happened several times that the mips code was broken due to changes of the generic code (see commits 97437bd17a8c5d4135b2f3b1b299bd7bb72ce02c and de262d018d7d7d9c967af1dfd1b861c4b9eb2a60 or 860dbe0275e57cbf4228f3f653f872ff66ca596b or 933309a6ca0f18bf1d40e917fff455221f57fb4b or b65ffa316e377213c29736929beba584d0d80d7c). This might even lead to scenarios where someone changing non-dsp aacenc code would have to modify mips inline asm in order to keep them in sync. This is obviously a significant burden (if the AAC encoder were actively developed). Finally, the code does not even compile here due to errors like "Error: float register should be even, was 1".
