Comment:
The problem is not in av_crc, but in shuffleplanes. It's not propagating
the palette plane despite being a pal8 stream.
./ffmpeg -i PoC_seg_crc_403.tga -vf shuffleplanes,showpalette -f null -
./ffmpeg -i PoC_seg_crc_403.tga -vf shuffleplanes -f apng -y /dev/null
All fail the same way, trying to access AVFrame->data[1], which is NULL.
