The MPEG-2 AAC profiles have been reused and became Audio Object Types in MPEG-4 Audio. Hence, any MPEG-4 Audio decor that supports those MPEG-4 Audio Object types is generally able to decode data encoded using the corresponding MPEG-2 AAC profiles. Best regards, Ralph -- Dipl.-Ing.

In ISO 14496-3 did mention that MPEG-4 CELP has a functionality of complexity scalibility. But I am not sure what are the switches related to this. I understand that this complexity scalibility means a possiblity of running the decoder at different complexity levels. One more thing, not quite understand with bandwidth scalibility, if anyone can helpl, how it works. Though in the README_usage has shows how to use bandwidth scalability. Just to double check with anyone who can help. Basically, MPEG-4 features this 4 functionalities i.e. bit-rate scalibility, multiple bit-rates, bandwidth scalability, and complexity scalability...

I have been working on an MPEG-4 based implementation and I have some questions regarding MPEG-J. I would be glad if you can provide me information regarding this. 1. Using the open source MPEG-J api's at ISO , the mpeg-j stream was only compiled using the bif enc and MUX. Hence the output was a .trif file. Is there a way to directly generate a MP4 file instead of a .trif file. I am not able to figure out how to do this. [Mika?l Bourges-S?venier] You should use mp4enc rather than mux. It will write Jar files into the mp4 file format. 2. If I use the .bt format and use the MP4 tool at ENST, how do I include a java stream to the mpeg-4 stream. [Mika?l Bourges-S?venier] Convert .bt file format to IM1 file format. There are almost the same for the scene description but the object descriptor section is a bit different, see the examples for MPEG-J in Test/MPEG-J directory. With IM1, you need 2 files: one for the scene description, which would be used by BifsEnc and one file for object descriptor which is used by mux or mp4enc (these files typically ends with .scr extension). It is in the scr files that you describe MPEG-J stream, see the samples in Test/MPEG-J directory.

Try encoding a test sequence, such as ferris, with one of the reference encoders (Microsoft or MoMuSys) with half-pel switched off, as an example. You definitely need to support it in the simple profile decoder. Not doing half-pel is usually an attempt in software encoders to avoid doing the high CPU intensive half-pel operations. The MPEG-4 spec contains some alternatives in Annex I, I believe, such as early exit..but of course never as good as doing the full search with half-pel, typically as with hardware encoders.

The way the interpolation is performed in ffmpeg is different than the way it is done by the ISO MPEG4 reference decoder. Specifically, the ffmpeg code will do all neccesary 8-tap filtering prior to doing any bilinear interpolation. However, in the ISO MPEG4 reference decoder all 8-tap filtering for the horizontal direction will be performed followed by bilinear interpolation in the horizontal direction. The results of this are then fed to the vertical 8-tap filter, followed by the vertical bilinear filter. Can anyone comment on what effect this different implementaion may have? I have consulted the specification and it is unclear to me. Looking at numerical outputs the two implementations do produce different results.

The problem was reported to video committee for over one year. After discussion by the committee, we decided to follow the reference software due to the following reasons. 1. most programmers realized their codec by referring to the software. 2. the conformance bitstreams are mostly generated by this way. 3. the adopted one processes horizontal filtering first then followed by vertical filtering. This way is logically simple and more regular, compared to what is originally specified by text or now adopted by AVC. As a result, video committee issued the V2/COR2 and V3/COR1 to make this aspect more clear. We believe now the text and software are consistent. As to the implementations by other public or commercial softwares, they should be changed accordingly, e.g., divx fixed its implementation in version 5.0.3. what effect the two different implementaions may have? This is an interesting question. I have no idea about how ffmpeg does now, but I believe the difference between the two is not too much, because both methods will use the same 8x8 pixels to generate a predicted sample. If any one has more experiences of this, pls kindly make your comment.

Just check if these were ON in the bitstream that you had inserted into .mp4 file, although by looking at the nature of corruption I don't feel this may be the problem. Secondly, first try to decode the MPEG-4 compressed bitstream with a Simple Profile Decoder and view the decoded output to ensure that the Encoder has generated the correct bitstream.

Also, together these standards replace and override Clause 13 of ISO/IEC 14496-1, in which the MP4 format was previously specified.

Infact the source code for those viewers is also avaliable. About the format, it is as follows. Lets say the picture resolution is W x H (Width x Height) and 420 format, first W*H bytes represent the luma part, next (W * H)/4 represent Cr and next (W * H)/4 represent Cb.

It is really helpful. I have another question, can anyone give me some explanation about residual CAVLC coding? I understand how to code/decode total coeffs and tailing ones,also total zeros and run_before coding, but I am confused about the remaining coeffs coding. The standard (subclause 9.2.2) has a table 9-6, how to use the table? How to determine the level_prefix, what is the bit string used for? If the suffix is great than 0, how to decide it's bit stream? Can anybody give me a example or tell me where I can find detail explanation about this problem? Again, thank you guy's help. Have a great day.

Message-ID: Hi, I'm currently designing a sub-system, which among other things, is supposed to support transport of MPEG4 video stream over IP. The stream is supposed to be sent to H.323 endpoints, SIP endpoints and Streaming Servers. As I understand, there are two RFCs dealing with MPEG4 over RTP: 1. RFC 3016 (the simpler one) Which "...enable transport of MPEG-4 Audio/Visual streams without using the synchronization and stream management functionality of MPEG-4 Systems." 2. RFC 3640 (robust one) Which allows transport of some other elementary streams such as system streams, BIFS, OCI, OD and IPMP. - Which RFC is supported by common H.323/SIP endpoints ? - Assuming RFC 3016 is appropriate for MPEG4 video over RTP, what is the puspose of RFC 3640 ? - Are there any terminals which support RFC 3640 ?
