If XVID_SAFE_BS_TAIL flag is defined (disabled by default) a cross check is performed before accessing *(bs->tail+2). However, this additional check will cost performance.

As i know, there is not an completed edtion of xvid for wince yet, although a lot people are working on this.

Content-Transfer-Encoding: quoted-printable Hello, the latest quantize_mpeg_mmx.asm crashes on my PC. The cause is the "cmovg" opcode used into quant_mpeg_intra_mmx() function= . I suggest the following change, which should be as fast as the P2 opcode = (perhaps a bit faster!) and also fixed my problem. Small note: if you look into the changed code, you will see that the sign= -extend of EAX into EDX has been done with a copy-shift instead of CDQ. I= made it because I think it's better since these two opcodes can be paire= d safely to others, while CDQ cannot be paired to anything.

Is it really required or it could be changed with a multiply with the inverse of the divisor? While I was going to write this message, I saw that quantize_mpeg_xmm.asm isn't using an IDIV opcode, but it already has what I'm currently suggesting. I don't know how much big could be these two numbers, so I wonder if it could be done. Sincerely, Carlo Bramini. PS: Although I didn't write it previously, I would like to thank you now. You may ask me: "Why???" It's simple, I saw that you added my name too into the header of cbp_mmx.asm Thanks a lot! It's really a great honor for me! Sorry for these delayed greetings... ------------------------------------------------------ Mutui a tassi scontati da 30 banche.
