++ /* Certain versions of FFmpeg have a bug in libswscale which ends up in crash
++ * when destination buffer is not properly aligned. For example, this happens
++ * in FFmpeg 4.3.1. It got fixed later on, but for compatibility reasons is
++ * still best to avoid crash.
++ *
++ * This is achieved by using own allocation call rather than relying on
++ * IMB_allocImBuf() to do so since the IMB_allocImBuf() is not guaranteed
++ * to perform aligned allocation.
++ *
++ * In theory this could give better performance, since SIMD operations on
++ * aligned data are usually faster.
++ *
++ * Note that even though sometimes vertical flip is required it does not
++ * affect on alignment of data passed to sws_scale because if the X dimension
++ * is not 32 byte aligned special intermediate buffer is allocated.
++ *
++ * The issue was reported to FFmpeg under ticket #8747 in the FFmpeg tracker
++ * and is fixed in the newer versions than 4.3.1. */
