Best regard xiongshu deng To interpolate the whole picture into halfpel (frame-based) is only useful (meaning faster) for doing HalfPel Motion Estimation where many positions have to be checked, not for Motion Compensation where only 1 halfpel position per block is needed. So for Compansation alone, block-based halfpel calculation is faster. In normal Motion Estimation, we only use Luminance to find motion vectors, so we only interpolate Luminance frame based, and the chrominance we do block-based, if it's needed at all. gruel _______________________________________________ XviD-devel mailing list XviD-devel@xvid.org http://list.xvid.org/mailman/listinfo/xvid-devel From xvid-devel-bounces@xvid.org Fri Jan 21 20:55:34 2005 Return-Path: X-Original-To: itdp@fh-biergarten.de Delivered-To: itdp@localhost Received: from edu.bnhof.de (edu.bnhof.de [213.167.167.52]) by mail.kliche.org (Postfix) with ESMTP id 59BF8126D82 for ; Fri, 21 Jan 2005 20:55:34 +0100 (CET) Received: from edu.bnhof.de (localhost [127.0.0.1]) by edu.bnhof.de (Postfix) with ESMTP id 0A941D974; Fri, 21 Jan 2005 20:55:28 +0100 (CET) X-Original-To: xvid-devel@xvid.org Delivered-To: xvid-devel@edu.bnhof.de Received: from dns1.tilab.com (dns1.tilab.com [163.162.42.4]) by edu.bnhof.de (Postfix) with ESMTP id 3F8C7D93D for ; Thu, 20 Jan 2005 19:49:13 +0100 (CET) Received: from [163.162.36.74] (borg.cselt.it [163.162.36.74]) by dns1.cselt.it (PMDF V6.0-025 #38895) with ESMTP id <0IAM00I1RFZ13W@dns1.cselt.it> for xvid-devel@xvid.org; Thu, 20 Jan 2005 16:21:01 +0100 (MET) Date: Thu, 20 Jan 2005 16:23:33 +0100 From: Mauro Borghi To: xvid-devel@xvid.org Message-id: <41EFCCF5.2010308@tilab.com> Organization: Telecom Italia Lab MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=us-ascii Content-transfer-encoding: 7bit X-Accept-Language: en-us, en User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922 X-Mailman-Approved-At: Fri, 21 Jan 2005 20:53:26 +0100 Subject: [XviD-devel] high-definition decoding bug?

I managed to encode in 2-pass, enabling up to 2 consecutive B-frames. Using xvid to decode the sequence, I get a crash on various players (both on win32 and linux). I placed the start of this sequence on the web (~5MB), so you can download it if you want to reproduce the crash: For example, mplayer on linux exits like this: [...] MPlayer interrupted by signal 8 in module: decode_video - MPlayer crashed by bad usage of CPU/FPU/RAM. [...] which should be a division by zero or some other floating point exception. btw, mplayer on linux needs to be run with the following command: $ mplayer -vo x11 -vc xvid hd-1080-xvid-2b.avi [trying to use the xvideo extension results in an earlier exit of the player, because of allocation errors in xv] Decoding using a different decoder (-vc ffodivx), the decoding crash disappears (though artifacts appear on the frames). Re-encoding the same sequence, but this time disabling b-frames, the decoding crash disappears. Another difference between "-vc ffodivx" and "-vc xvid" is that while with the former the colorspace and image size are ok, with the latter the colors are messed up and the image size is half in width of what should be. (But probably this is an mplayer issue, as with other players this does not happen). Hope this helps finding the bug... if it's actually a bug!

the application would query machines on the network that are not using their cpu fully and would seize this opportunity to distribute the load efficiently.. the aim would be to reduce compression time.. by splitting the movie intelligently over the network and making the other machines other than the original machine do the job.. does any tools like this exist?

Transcode AFAIK has such a feature, that you should be able to use smoothly thought the GUI dvd::rip (http://www.exit1.org/dvdrip/) Other than that, you may want to look at the following thread to build an application to do some distributed computing thanks to MEncoder (http://thread.gmane.org/gmane.comp.video.mplayer.devel/19937). To the best of my knowledge, the patch hasn't been sent to the ML, bu should you send a private mail to Antoine Duchâteau, he might send you his patch. Anyway, what I'm trying to say is that AFAIK, you don't need to integreate that king of feature directly into XviD... Let us know how you projects turns out.

If done right, it could be used as an intermediate format to "edit" MPEG-4 on the binary level without having to recompile the stream. It would also be great for research, e.g. to analyze motion fields. Or, since the first is quite a task, how about a binary level editor for internal MPEG-4 header parts, like aspect-ratio? I _hate_ it when encoding a stream, and then after 5 hours notice that the aspect-ratio was set wrong. This is essentially just 1 bit thats wrong, but I have to encode the whole stream again, because there's no too to locate and change this bit. :-( Next idea, which I don't know if it has been tried: An MPEG-4 to MPEG-4 reencoder unit, just like there are available for MPEG-2 (DVD9->DVD5). It would come handy in 2 cases: First, when encoding on the fly in high quality (like fixed quant 2), to reencode to smaller bitrate later. Second, if e.g. a DVD rip turned out a few MB to be too large, one could use this to reencode certain parts at slightly lower bitrate without having to reencode everything else. gruel _______________________________________________ XviD-devel mailing list XviD-devel@xvid.org http://list.xvid.org/mailman/listinfo/xvid-devel From xvid-devel-bounces@xvid.org Fri Jan 28 10:03:24 2005 Return-Path: X-Original-To: itdp@fh-biergarten.de Delivered-To: itdp@localhost Received: from edu.bnhof.de (edu.bnhof.de [213.167.167.52]) by mail.kliche.org (Postfix) with ESMTP id CFF98126D82 for ; Fri, 28 Jan 2005 10:03:24 +0100 (CET) Received: from edu.bnhof.de (localhost [127.0.0.1]) by edu.bnhof.de (Postfix) with ESMTP id CDDF8D946; Fri, 28 Jan 2005 10:03:21 +0100 (CET) X-Original-To: xvid-devel@xvid.org Delivered-To: xvid-devel@edu.bnhof.de Received: from hugin.optimalstream.net (unknown [130.226.208.162]) by edu.bnhof.de (Postfix) with ESMTP id 77C65D93C for ; Fri, 28 Jan 2005 10:03:18 +0100 (CET) Received: from maersk-moller.net (IDENT:1121@localhost [127.0.0.1]) by hugin.optimalstream.net (8.12.10/8.12.4) with ESMTP id j0S93I8q004075 for ; Fri, 28 Jan 2005 10:03:18 +0100 Message-ID: <41F9FFD6.2040909@maersk-moller.net> Date: Fri, 28 Jan 2005 10:03:18 +0100 From: Peter Maersk-Moller Organization: Kabel-TV over Internettet User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624 X-Accept-Language: en-us, en MIME-Version: 1.0 To: xvid-devel@xvid.org Subject: Re: [XviD-devel] Project Idea References: <94049b6105012701106e94ae5b@mail.gmail.com> <41F8FD24.6090801@gmx.at> <94049b61050128001513e4ff54@mail.gmail.com> In-Reply-To: Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit X-BeenThere: xvid-devel@xvid.org X-Mailman-Version: 2.1.4 Precedence: list Reply-To: xvid-devel@xvid.org List-Id: xvid-devel.xvid.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: xvid-devel-bounces@xvid.org Errors-To: xvid-devel-bounces@xvid.org Status: O X-Status: X-Keywords: X-UID: 703 Hi Christoph Christoph Lampert wrote: > On Fri, 28 Jan 2005, JP wrote: > Or, since the first is quite a task, how about a binary level editor for > internal MPEG-4 header parts, like aspect-ratio? > I _hate_ it when encoding a stream, and then after 5 hours notice that the > aspect-ratio was set wrong.

The extra bytes needed in extended PAR mode is usually not present in normal PAR mode. But such a tool as OS would be cool and if based on xvid and the mp4v2 lib from mpeg4ip, then maybe not that hard to write. --PMM _______________________________________________ XviD-devel mailing list XviD-devel@xvid.org http://list.xvid.org/mailman/listinfo/xvid-devel From xvid-devel-bounces@xvid.org Fri Jan 28 10:21:39 2005 Return-Path: X-Original-To: itdp@fh-biergarten.de Delivered-To: itdp@localhost Received: from edu.bnhof.de (edu.bnhof.de [213.167.167.52]) by mail.kliche.org (Postfix) with ESMTP id 33533126D82 for ; Fri, 28 Jan 2005 10:21:39 +0100 (CET) Received: from edu.bnhof.de (localhost [127.0.0.1]) by edu.bnhof.de (Postfix) with ESMTP id E78C6D959; Fri, 28 Jan 2005 10:21:35 +0100 (CET) X-Original-To: xvid-devel@xvid.org Delivered-To: xvid-devel@edu.bnhof.de Received: from grunt24.ihug.com.au (grunt24.ihug.com.au [203.109.249.144]) by edu.bnhof.de (Postfix) with ESMTP id 66910D947 for ; Fri, 28 Jan 2005 10:21:32 +0100 (CET) Received: from dsl-153.160.240.220.lns02-waym-adl.dsl.comindico.com.au [220.240.160.153] by grunt24.ihug.com.au with esmtp (Exim 3.35 #1 (Debian)) id 1CuS1j-0004Cl-00; Fri, 28 Jan 2005 20:02:52 +1100 Message-ID: <41F9FFFD.8060402@ihug.com.au> Date: Fri, 28 Jan 2005 19:33:57 +1030 From: Radek Czyz User-Agent: Mozilla Thunderbird 1.0 (Windows/20041206) X-Accept-Language: en-us, en MIME-Version: 1.0 To: xvid-devel@xvid.org Subject: Re: [XviD-devel] Project Idea References: <94049b6105012701106e94ae5b@mail.gmail.com> <41F8FD24.6090801@gmx.at> <94049b61050128001513e4ff54@mail.gmail.com> In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-BeenThere: xvid-devel@xvid.org X-Mailman-Version: 2.1.4 Precedence: list Reply-To: xvid-devel@xvid.org List-Id: xvid-devel.xvid.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: xvid-devel-bounces@xvid.org Errors-To: xvid-devel-bounces@xvid.org Status: O X-Status: X-Keywords: X-UID: 705 Christoph Lampert wrote: > Or, since the first is quite a task, how about a binary level editor for > internal MPEG-4 header parts, like aspect-ratio? > I _hate_ it when encoding a stream, and then after 5 hours notice that the > aspect-ratio was set wrong.

I know, I know - it exists (2 pass right). But that's not what I mean. To my understanding 2 pass takes the input bitrate as a avg it intends to meet. It then analyzes the video determining what parts of the video need what bitrate then on the second pass varies the quantizers as need to achieve that overall bitrate (more or less correct?). It's been stated that 2 pass has a method of determining what level of quantization a macro block should have (to retain high quality). Could this not be determined "on the fly" during a single pass encode to allow instead of a fixed quant but rather a variable quant + variable bitrate mode? Which would use the lowest needed quantization for a macro block while still allowing for higher ones to be used when possible. This way it is possible to have a high quality single pass fixed quant 2 without wasting bits. Thanks for your time in advance, Lee P.S.
