[Mp4-tech] Is there any tools transfer ethreal Video RTP streams to raw data ?

[orho.ms1]

Dear All,
Is there any tools transfer ethereal Video RTP streams to raw data ? 
I need the tool to extract the video streams such as H.263, H.264, MP4. 
Is there have any tools to filter from ethereal than can feed to TMN /
TML / ...?
Sinerely,
Orho

  Hi John,
    There could be a variety of reasons for this:
(1)  In MPEG-4 Simple Profile, the max bit rate that a decoder is
required to support is 384 kbps. 950 kbps is too high a value, and it's
diffucult to say how the MPEG-4 decoder used in QuickTime 6.3 Player or
RealOne Player will react.
(2)  Blockiness may also result if the Rate Control Algorithm used in
that MPEG-4 Encoder is not up to the mark for some particular cases,
like in this instance, 950 kbps and QVGA encoding.
(3)  Your PC Specifications, as far as Processor Speed is concerned, are
at a lower end. What is the frame rate of the MPEG-4 video stream? If
fps is large and given the fact that bit rate is also high and VOL
width/height is 320 x 240, then playback may not be as desired....
  I suggest that you decode the MPEG-4 Simple Profile bitstream using an
MPEG-4 reference video decoder and play the decoded sequence in some YUV
4:2:0 player....
  Regards,
  Parag.
