...which usually calls a platform-specific version via _enc->opt_vtable.fdct8x8, though on some platforms, it will call a specific version directly (e.g., oc_enc_fdct8x8_x86_64sse2 on x86-64). All of the functions with platform-specific accelerated versions work like this. If you want to force oc_enc_fdct8x8_c (the unaccelerated version) to be called, then build without assembly optimizations enabled (e.g., pass --disable-asm to configure).
