History

Andreas Rheinhardt b9c1ab8907 avcodec/fft_template, fft_init_table: Make ff_fft_init() thread-safe ... Commit 1af615683e put initializing the ff_fft_offsets_lut (which is typically used if FFT_FIXED_32) behind an ff_thread_once() to make ff_fft_init() thread-safe; yet there is a second place where said table may be initialized which is not guarded by this AVOnce: ff_fft_init_mips(). MIPS uses this LUT even for ordinary floating point FFTs, so that ff_fft_init() is not thread-safe (on MIPS) for both 32bit fixed-point as well as floating-point FFTs; e.g. ff_mdct_init() inherits this flaw and therefore initializing e.g. the AAC decoders is not thread-safe (on MIPS) despite them having FF_CODEC_CAP_INIT_CLEANUP set. This commit fixes this by moving the AVOnce to fft_init_table.c and using it to guard all initializations of ff_fft_offsets_lut. (It is not that bad in practice, because every entry of ff_fft_offsets_lut is never read during initialization and is only once ever written to (namely to its final value); but even these are conflicting actions which are (by definition) data races and lead to undefined behaviour.)
