I'm copying a couple of key MPEG people so that they will record the report of a MoMuSys software bug. If you can describe the bug more precisely to them, it might help. E.g., is it an encoding problem or a decoding problem? (Presumably decoding?) The obvious way for an encoder to use it to improve coding efficiency is to count the bits for coding the picture with both VLC types for each value of QP and pick what gives the best result. However, that may not be a practical expectation for many implemenations. The value of the feature would depend not only on to what extent it provides coding gain in coding the intra macroblocks, but also how much of the video is coded as intra -- if the video doesn't contain periodic intra pictures and if the bit rate is low enough that few macroblocks are coded as intra within non-intra pictures, then it won't help much.

I don't think that this is a normative issue. The decoder has to provide the player with information about width and height (and other info conveyed in the headers) and with the actual video frames. But the standard does not specify how to do that. So the answer to your questions is: It depends on the API of the decoder you are using.

Hi there, While reading papers about FGS (bit-plane method) in Mpeg 4, I am wondering where it is possible that by using a large Quantization Parameter, we reduce the bit rate of Base Layer to send it through a low rate channel. Sure that will make the BL less valuable in terms of video quality, but this will also make BL more reliable through a lossy network. Is that right or not? Thank you! _________________________________________________________________ ÓëÁª»úµÄÅóÓѽøÐн»Á÷£¬ÇëʹÓà MSN Messenger: http://messenger.msn.com/cn _______________________________________________ Mp4-tech mailing list Mp4-tech@lists.mpegif.org http://lists.mpegif.org/mailman/listinfo/mp4-tech -------------- next part -------------- An HTML attachment was scrubbed...

Here is my suggestion: Open the Microsoft VC++. Drag the bitstream into VC++. If you can find some readable four byte combinations, e.g., "ftyp", "uuid", "mp4v", "mp4a", "mdat", etc, then this is MPEG-4 System file. You can download the "mpeg4ip" software, in which there is a MPEG-4 Demux. Otherwise, it is nother media format, maybe MPEG-4 AAC, or MPEG-2 audio. You need to check the spec. and bit syntax very carefully. On Wed, 12 Nov 2003, ramesh raman wrote: > Hi, > Thanks for the quick response.

First, thanks for going through the trouble of providing answers. Then, please note that this is a public list. Often, non-MPEG members will ask questions. One might even say that the list was created for non-MPEG members. References to MPEG documents are only really helpful if: * you are sure they are public documents * you give a reference to where they can be found. sometimes, referring to the standard may be acceptable. Please also mention where the answer can be found in that case. (Indeed the MPEG-4 standards are not public.) In this case, N4699 is the working draft for the third edition of MPEG-4 systems - quite a sizable document. Yes, it is public in principle, but I wouldn't know where to find it online ... MPEG has no website that keeps track of all past public documents.

Message-ID: (if this message is duplicated, sorry for that...) Hi friends, I am doing some research on packet scheduling for MPEG4 stream in order to obtain a best quality video. I need your help: 1) A question: In MPEG4 sub-streams could be encapsulated into packets of same size. Is this right? Where can I find surpporting information? As far as I know, MPEG4 standards only defines decoding of bit stream. 2) Now I want to obtain a pure MPEG4 video stream, coded into a BL and an EL, under bit-plane encoding scheme. 3) Then I want to packetize BL and EL into fix-size packets, and count the packet number of every frame. By frame I mean a static picture. For 2 and 3 any suggestion about tools will be appreciated! Do the following analyzers offer such kind of functionalities?

I have a few doubts about the GMC decoding. In section 7.8.7.3 of MPEG 4 specification ISO/IEC 14496-2 it is written that macroblocks with mcsel = = 1 don't have their own block motion vectors, they have pelwise motion vectors for sprite warping obtained from global motion parameters. But in section 7.8.6 in the description of the method for sample reconstruction Y and C values are calculated directly . My question is how to calculate the global motion vectors for every pixel of the macroblocks with mcsel = = 1 and how exactly the global motion compensation is done using these motion vectors?

On IPAQ, the release has an XVid video decoder (slower but resists to missing packets when streaming) and an OpenDivx video decoder (faster but easy to crash). As usual, there is an MP3 decoder for audio. And it has a quite awesome performance in BIFS. We have tested the IPAQ version with the Telemak streamed content (on an IPAQ 3630 with Wifi and Xvid), and it works quite well... Please visit the Osmo4 page to try it out. http://www.comelec.enst.fr/osmo4/ I believe it is the first *free* MPEG-4 Systems player on IPAQ/Pocket PC.

Because IndexedFaceSet is a 3D node... You need a 3D player for what you are trying to do. A free one (but not fast) is the reference software, an exe of which you can download from: http://www-artemis.int-evry.fr/~preda/MPEG-4/ Octaga has a 3D MPEG-4 player that does not implement ODs (so it is not really MPEG-4). BitManagement has a 3D MPEG-4 player with ODs, and mp4tool was created in the same project (SoNG) so they are compatible. However, neither is free.

As I said it is targeted only for video and audio support. One of the intersting solutions would be to use Quicktime 6.4 API to perform decoding and demultiplexing. My first move was to evaluate how Quicktime behaves itself regarding .mp4 and .3gp files. So I went to Envivio and Philips and downloaded their video samples (including interoperability samples). My current success rate is only that 50% of the files play correctly. Does anybody could give more details about issue ? Is Quicktime late regarding interoperability or are the Envivio and Philips samples outdated ? My second question is perhaps more [MP4-discuss]-oriented but nevertheless since it regards Quicktime, I'll ask it there. As far as I know, usage of MPEG-4 involves licensing fees to be paid to MPEG-LA. If I use the Quicktime API including MPEG-4 and 3GP support, do I get it for free since I suppose Apple already pays for the license ?

You should probably look at the terms for the license, and explaining any license is a hazardous undertaking. QT, in its click-through license, has a statement on what you can and cannot do without without paying additional fees. It depends entirely on you specific usage. You might want to contact MPEG LA directly.
