"Protecting" your code only makes sense if you either...
(1) plan to sell your software commercially (2) need to hide your algorithms from your antagonist (e.g. decryption software) (3) want to hide malware in your software In case (1) you could simply buy a license for one of the commercial executable protectors/obfuscators (e.g. ASProtect). That still won't give a "safe" protection, of course. But I'm sure it will be at least as hard to crack as your own protection. And it saves you trouble/work. Also since many (commercial) applications are protected with such tools, the chance that any A/V software will complain is very low. Case (2) certainly doesn't apply to a H.264 decoder, so I have to speculate that we have a case (3) here...

These "Protection" Software they sell is bogus you can always disassemble the code, it's just money making same for all the other Commercial Protection Systems like Securom ,StarForce and others they just ad another layer of "imaginative Protection" we don't talk about the normal usage scenarios though here that justifies (in the eyes of the creators) these rootkit like systems, we talk about protection added so nobody can RE his code but that is impossible with the current computer hardware, so the competition of him will know how to do it he can't protect it it's not logic. And yes for a guy that does Assembly Coding and a thing like a H.264 Decoder it's strange, though CoreAVC and others do it too and they also know what they do (or don't sometimes i have the feeling it just makes them feel better todo anything than nothing even if it's absolute useless) but i would never pay for this wannabe protection or protect @ all as it makes absolutely no sense if someone wants to RE it he can as long as it's executed it can't be protected on current computer Hardware.

I never hide some malwares in the DiAVC, I have engaged in the software for several months and I want to sell it online in future, I will never risk my business. |

As long as you keep your codes in private and protect/obfuscate your binaries we can't prove that statement (easily).
But that applies to most commercial software... Quote:
But you should check your protected binaries at http://virustotal.com/ to avoid false positives and confusion. Also I'd recommend to test your binaries with DEP enabled...

VMProtect is also another of these security layers that's imho useless, but yeah Virtualization the new Buzzword so i need it Btw there is more then DEP they're lot of 3rd Party behavioral analyzers some of them will also go into alert mode but he's gonna see that from his customers feedback soon enough, you just run after something which can't exist on current hardware and that as a knowledgeable person is highly non logic Though how he writes shows what his main intention is "Business" so good luck vs your competition especially CoreCodec and DivX you should have joined ffmpeg and invest your potential energy into there then to waste it like this schweinsz (it's never to late ), of course that's your personal decision, nevertheless i wish you good luck and im out. Don't want to be responsible if Donald get's a heart attack, sometimes going of topic is unavoidable especially as in this case the thread starter is promoting something so i assumed he's also interested in general ideas and views about his future Software Product (from his Potential Con/Pro Customers)

if very efficient Divx h.264 decoder will be released for free I see no reason to pay for DiAVC or coreavc. You won't earn to much money.

On my system ffdshow-MT already achieves ~80% of the throughput of DivX's H.264 decoder: http://forum.doom9.org/showpost.php?...0&postcount=34 That's definitely fast enough for smooth real-time 1080p playback with pure software decoding. What do we want more?

I think I'll pass on a decoder that seems to have no actual benefit other than to possibly hide malware. Besides CoreAVC already works quite well for me, is professionally written, support, has a website that actually contains more than an archive and doesn't send my virus scanning program into a panic attack.
Anyway good luck but your pretty much just wasting your time. |

Interesting, but no thanks I have no need for a closed-source decoder, and I don't think I'm far off in thinking that the only reason many others on this forum do is because they want/need very high speed, which neuron2's GPU decoder offers. That said, I would suggest that you either open-source your filter (why closed-source if you don't plan to sell it? Or do you?), so any improvements you find can be shared among the community and all software is helped by it, or you make going closed-source viable - FAST decoding, even faster than the current fastest, which is neuron2's solution.

Sure he will have strong competitors, in the ClosedSource world and in the OpenSource world. But if he wants to take the challenge, why not?

Alright, but still, all I was offering is advice He of course does not have to follow my recommendations, they may very well be bad. IMO the only way he can compete in the payware world is to leverage GPU decoding. There are many big-name decoders, with big backing, so he needs to differentiate himself. Offering the _real_ fastest decoding is one way, and I don't think it's possible to do that without leveraging the GPU in some way. CPU fallback, sure, but GPU decoding must be implemented. He could even use libavcodec-MT for the CPU decoding (seems fairly safe legally), since it's LGPL, and contribute if he needs more speed - surely that would be faster than writing a CPU decoder from scratch?

@Ranguvar: Leveraging the GPU for helping decode is already done in a lot of free decoders though. So why should a consumer buy his product if they can get GPU based decoding for free? Yes, having GPU decoding would help improve the product, but the best way to differentiate from all the other decoders is to offer very fast software decoding and GPU based decoding.

Why is it that even after a moderator asks everybody to get back to topic the next 14 posts are still off topic?

- Virus contamination suspicions - Open Source hack suspicions with always the same stupid speech on open source (M$ is devil ... blablabla) It's really secondary question but the decoder work correctly ... lol
