[FFmpeg-user] Encoding v210 fails when using PIX_FMT_YUV422P16LE even though PIX_FMT_YUV422P10LE is deprecated

Never mind. The encoder expects planar data, so it was easier than I
thought. The reason it wasn't working before is because the endian order was
reversed for each unsigned 16 bit value (since v210 expects uint16_t). It's
working now with YUV422P10LE. Thanks for your help!
