However, I agree to say that the need for third party levels for AVC is a lot less dire than it was for ASP. Two years ago, it would have been another story, but now the processing power is there, so it's not necessary anymore.

The only problem I see with what you said Brother John is that other encoders aren't going to want to put "Certified to create DivX certified streams" in their products as that's free advertising and supporting the rule of law of the other company. Thereby creating a rift in the profiles as their companies adopt their own "standard profiles". It would be much better for them to just be able to say "Level 4.1 Compatible"

If we're talking DivX Certification here for a second, my thought would be that SD could be 4.1 or 4.2 High Profile compliant, and HD could be 5.1 High Profile compliant, thus keeping a wide spread of the H.264 standard's features. In practice, only the image size/frame rate and number of macroblocks and max bitrate changes between 4.1/4.2 and 5.1, the difference in bitrate and macroblock terms is 5.1 has 4x the macroblocks per second of 4.1, and 5.1 High has a max bitrate 6x bigger than 4.1.

It would be better to ask for 4.1 compatibility, but also ask that the players attempt to play videos even if they have higher levels. Nothing annoys me more than patching a 5.1 video to 4.1, and then it works perfectly. It's like, "Why didn't you just give it a shot at playing instead of running in fear from the big 5 1?"

The CE world is not as clear cut as you might imagine when it comes to H.264. There are many STBs that do not fully support High 4.1.

As far as player manufacturers are concerned I guess most won’t have a problem with DivX certification. But for example Nero might not be too keen to let their encoder produce »DivX certified« video. ChronoCross is right, that would be free advertising for the competition. But an industry wide joint certification program might be too much to hope for.

If AVC really wants to take off and have a decent market a universal non company specific standard must be used between encoders. |

And you miss my point: This covers hardly any companies. In fact, are there any beside Nero (who output .MP4 files and have their own "Nero Digital" standard anyway)?

@Digital56K: is DNX considering to make also a divx CLI encoder?

I'd ask if it's possible for Vorbis and AAC to get the look in on DivX Certified audio. Vorbis is not as common on standalones, and the Tremor fixed point decoder's been around for a long while. AAC could probably be the ideal multi-channel format, Vorbis the 2 channel format (although AAC is no slouch in this regard, there are different flavours that take different decoding requirements and more are being developed for different markets. Vorbis has not changed much), but they both have their own strengths and weaknesses.

vorbis... mkv... dunno. i'd prefer a more "standard" compliant output.
mp4 is the natural container for AVC/AAC. why not use that combo? MKV and vorbis are 2 outstanding techs and would be great to have them as a second choice though. however IMHO AVC/AAC in MP4 is the way to go.

... or any of a dozen+ other formats. IMHO (and without me going into details) using Matroska allows DivX a greater range of flexability without having to confirm to limited container possibilities. DivX has always been about pushing new ideas/concepts/projects (even though they have been quite this past year), this is no different.

Given that every digital surround sound amplifier offers onboard multi-channel AC3 decoding (and not AAC), AC3 is a must for any container.
Much as I like multi-channel AAC-LC and HE audio, I am happy that the MPEG-4 spec is at last being amended to officially accommodate AC3 (and EAC3) audio streams.

Thanks for the offer but that's really not necessary, you can watch subtitles for free O.O
