As far as I know, you don't have to perform a flush after encoding a terminal bit 0, only after a 1.

I'm trying to use the encoder on it's own, too. It compiles/runs fine,  
but sometimes there are errors. I'm doing this:

loop:
    x264_cabac_encode_bypass(&cabac, i)
x264_cabac_encode_terminal(&cabac, i)
x264_cabac_encode_flush(&cabac)

loop:
    i = x264_cabac_decode_bypass(&cabac)
i = x264_cabac_decode_terminal(&cabac)

sometimes, depending on wheher I use 1/0 in encode_terminal(), the  
decoded sequence isn't correct. Is there anything special I have to  
look for?

thanks
tom
