Hi karl_lillevold,

I have tried encoding anime clips using the latest Helix DNA Producer (10.0.0.545) with the aac addon. The codec flavor that I have tried are racc 0, racc 1, racp 0 and racp 1.

However, when playing the resulting rmvb files in Real Player 10 (6.0.12.872), the "clip source" shows that the sampling rate is 22050 Khz for racp 0 and 1, and 32000Khz for racc 0.

Stream: 1 Audio Stream
MIME type: audio/x-pn-realaudio
Max Stream Bit Rate: 64.0 Kbps
Audio Codec: (RealAudio) 22050 Khz

Is this only a bug in Real Player 10 that a wrong value is shown? Or the audio of rmvb clips are actually at 22050 Hz? Or 22050 Khz?
How can I verify the sampling rate of the clips?


Regards,
Daniel

the racp is in 22050 hz upsampled to 44100 while playing (like mp3pro).
i'm not sur realplyer fully support racp.
try to play your clip with mpc + coreaac

Thanks for your reply. I have searched this forum using the keyword "mp3pro" and found much more information on this issue. Thanks a lot.



Edit:
I have tried playing the anime clips using MPC with coreaac and mpc's internal aac decoder. The AAC+SBR and upsampling 22050 -> 44100hz info can be found in the coreaac property sheet. Moreover, the audio quality of racp 0/1 (just by my ears ) when playback in RP10 is about the same as in MPC. So I think RP10 now fully supports HE-AAC playback. Thanks again for your help.

Another question:
Can I assume that racp is better than raac at 96Kpbs, and racp is not useful at 128Kbps? Is this just a subjective opinion and cannot be compared at a technical point of view?

Just test with your ears raac@128 vs racp@128, if the 2 are for you equivalents, use raac (lest cpu usage while encoding & decoding)

I think the fact Helix is developing RV10 toghether with this community is very appreciated.

Congrats Karl.

[EDIT] Oh, sorry for posting this so late, hehe. I've been quite busy.

Could Helix Team take measures against hybrid material more and more ?

At the present time, correspondence is WMV9's interlace maintain mode only.
if RV10 deal with hybrid material, I can recommend RV10 for anime freaks in my community.
but most people of them are using WMV9 now

lunaticmoon: Please see my reply in the other thread, where I asked you to explain the problem in other words. Producer's auto de-interlace and IVTC filters are designed to take care of video consisting of both interlaced and telecine'd material mixed together. It can also encode VFR without any problems. This is why the problem is not clear to me, and I need to understand it better, and what hybrid material means. Thanks.

Can I make a stupid off topic question?

Don't you guys at Real have any interest on competing with WM9 for the HD-DVD format? I think it is a lot more mature than WM9 since there has been a massive development on it.

Of course being able to mux RealVideo and RealAudio into Matroska with this plugin is just a coincidence
Seems this don,t exist anymore

Yes, corecodec has been down and the new server has only been online. Hopefully we'll have the old projects back in soon, so the link will work again.
Dunno if I still have a binary of this on my hd.

I edited the post I wrote about mkv-writer in the Containers forum, to reflect the new download location. Thanks again, jcsston!

an old question by iradic (sorry for the delay):
Quote:

the rmrepair version can read RM files, will either re-code (trans-code) or trans-script (re-package). The RM files can be normal, or broken, that is the result of a crash during the encoding, such that they have not been finalized.

Possible to choose quant interval (I,P,B) for second pass encoding in next version of RV10E ... ?

Sagittaire: I am afraid I don't quite understand your question.. Could you try to clarify?

EDIT: If what you mean is like set quant 1-3 for I, 2-12 for P, 3-14 for B, then I would have to look into it further, but perhaps that could be added, if someone would find it useful.

Hi,

Although a longstanding "DivX man", I'd heard so many good reports about RV10 that I thought I'd give it a look. First tried to install the 'freebee' basic RealProcuder but I couldnt open up the program -exe. generated errors. So tried AutoRV10 instead and I'm very impressed with the results. I have several (naive) questions:

1. Are there any standalone DVD-MPEG4 players that can playback RV10 video. If not, is this something that could feasibly be introduced as a firmware upgrade or does it involve a totally different decoding technology (like I said, naive).
2. I'm always on the lookout for alternative ways to play videos on my pocket pc (iPAQ3970). I'd actually removed the Mobile RealOne Player that came with it, mainly because its usefulness seemed to be limited to wireless streaming of the occasional emdedded realmedia clip, which at current GPRS rates in my locality is a very costly luxury. Even so, I thought I would chance my luck and encoded some test clips with AutoRV10 at various resolutions (320x240, 240x180, 320x176) and bitrates (180 - 250) with and without realaudio at 44kbits/s, 48KHz stereo. None would play on the mobile player. Is there any prospect of a RealMedia player for pocketpc that is able to play RV9/10?

Thanks.

Yes ... exactly ... but not necessary for each frame type

rcMinQuant and rcMaxQuant for exemple
