Hi,
I cannot send all the live555 package compiled on my board. Attached is the
executable file live555MediaServer, put it any where on your board and run it.
Let me know if there's any problem or you make any progress :).
Regards,
Viet Hoang

I do not know exactly what you meant for "your setup". You meant
live555MediaServer, or all the configuration used to test mpeg4 streamed from
recorded file?

Viet Hoang.

it would be nice to have a copy (or some explanation) of your setup

Hi all,
Prateek, did you really try this (using live555MediaServer)?
Here are what I tried and failed:
1) Record a short .mpeg4 clip using DM355, change the file's extension to
.m4e and copy the file to live555MediaServer's directory, run
live555MediaServer and then on a Windows PC use VLC to play that file using
RTSP: FAILED - I didn't see any data received at VLC site.
2) Copy file davincieffect_ntsc.mpeg4 from /opt/dvsdk/data/videos/ to
live555MediaServer's directory, change the extension to m4e, run
live555MediaServer and use VLC to play that file: FAILED.
3) Play back those 2 files using ffplay (from ffmpeg) on Fedora 5: OK.
Play back those 2 files using VLC 0.8.6f on Windows: FAILED.
4) Try 1 and 2 using files from DM6446, work well.
I think 1 & 2 are due to the one-time sent VOL header as Antonio said. Is
this due to the Beta released version of DM355EVM and mpeg4 codec? Do you have
any idea how to fix this?

Viet Hoang.

I will suggest looking at
http://www.live555.com/mediaServer/
Open source C++ libraries under LGPL to support RTSP streaming. There are test
programs that are available with this library that can be easily cross-compiled
on Montavista Linux platform. You can use the test program to stream MPEG4
elementary stream file contents generated by DM355 encoder and can be played
back using any PC client like VLC, Mplayer to playback the stream contents.

Subject: Re: DM355 MPEG-4 Streaming
Thanks
but I would not like to go and build a new RTP/RTSP etc stack on my own... I
an sure there are readymade stacks like these on the net. I have heard of
live555 and others.
Any ideas ?

The most helpful resources are RFCs from IETF. I can point you out the most
important rfc's about the subject you pretend.
RTP: rfc1889
RTSP: rfc2326
SDP: rfc2327 (this is useful for rtsp or multicast streams)
RTCP: rfc3550
Then, depending on which standard are you working at (MPEG-4 SP, AVC) you have
to verify the corresponding RFC to see how to packetizes the encoded frame.

hi all
can somebody explain a little about video streaming in general, or give us
some pointers?
Especially on rtp, rtsp, and different kind of media
thanks all

Hi all,
I am trying to perform a test which consists in perform an MPEG-4 Encoder &
Streaming application using the board DM355.
I already worked with an H.264 Encoder & Streaming application, and with
H.264 we have sps and pps periodically transmited which allows a client to
receive the stream even is the sender is not at the beggining of the
transmission.
In MPEG-4 we only have the MPEG-4 header (I think is VOL header) at the
beggining an then we just have VOP headers. The receiver cannot receive the
stream if he dows not get the VOL header.
My question is, how can we do this using the MPEG-4 Encoder at DM355? Does
anybody knows the size of the VOL header generated by the encoder at DM355??
Thanks in advance,
A.Silva
