h.264 in mpeg-2

[tonykwon]

Hello,

This is the first time in VideoLAN Forum for me.
I think I found a cool site...!!! Many thanks to VideoLAN.

I have 2 things requesting your advice.

=== 1 ===
Nowdays, I'm working for Korean DMB(Digital Multimedia Broadcasting)
solution especially for the DMB receiver. So, I'm first trying
to build the VLC media player on cygwin and it's working good.

But, after all I have to modify the source code for it to work
at Korean DMB streaming environment(streaming H.264/BSAC
in MPEG-2 TS). I think I have to first demux incomming stream
and transfer the elementary stream to the decoder. ...
Now, I'm very confused because I couln't find the clue in source.

If you have any advice, Please talk to me some...

=== 2 ===
And I tried to save ES stream in MPEG-2 TS with command line like,

./vlc.exe -vvv MPEG2.ts --sout='#es{access_video:file,mux_video=ps,url_video=video-%c.%m}'

but, it failed....! Only 4 byte output file created.
I'd like to split out specific element stream in MPEG-2 TS
which normally has many programs.
Please teach me how I can get the specific
Elementary Stream in MPEG-2 TS file.

As far as I know, vlc (at least 0.8.0-test1) should support h264 in mpeg2-ts. Could you post the log produced by playing such a stream in vlc if it don't work in latest version?

I am a beginner ,learning H.264.
Here are some questions:

1) When streaming H.264 video over MPEG-2 TS, I try to put H.264 video into PES,then put PES into TS. Is it right? If not, please tell me sth. about the detail.

2) I am confused about the module Packetizer/H.264.c and Demux/MPEG/H.264.c, what are they doing?

Thanks for help

In vlc 0.8.4a, I search to play a DMB file (H264 + HE-AAC V1 in MPEG-2 TS) and I obtain this error :

The description of the MPEG-2 TS stream is done by the ETSI specification TS102 428.

If you want I can provide a sample stream.

DMB is a seperate specification (just to keep things simple ) that is not yet supported by VLC. If anyone wants to add the appropriate descriptors and framing support to libdvbpsi and VLC, he is welcome to do so.
