Thanks, I will try that. Though I could live with undefining ARCH_X86 in cabac.h

Unfortunately, another H264 decoding problem showed since R6655 when decoding the same sample file:
[h264 @ 007104A0]top block unavailable for requested intra mode at 0 0
[h264 @ 007104A0]error while decoding MB 0 0, bytestream (9012)
[h264 @ 007104A0]concealing 510 DC, 510 AC, 510 MV errors

Guillaume, would you mind testing this sample in ffplay?
