[vlc-devel] VOD streaming on m3u file

[Arieh Skliarouk]

Hi,

(this message is different from one I posted several days ago about
segmentation fault of vlc 0.8.6c in the same scenario).

I have compiled vlc-trunk that I have checked out at 20070922 (yesterday).

Attempt to stream playlist (m3u) as VOD from vlc to vlc does not work, as
vlc client produces strange error (see below). Here are the steps that I
undertook:

1) Start vlc in daemon mode
vlc --ttl 12 -vvv --color -I telnet --telnet-password videolan --rtsp-host
0.0.0.0:5554

2) Create file "b.m3u" in the same directory where vlc in step 1 was started
from:
music1.mp3
music2.mp3

3) Made sure that files music1.mp3 and music2.mp3 exists in the same
directory as b.m3u

4) Set up VOD streaming of the b.m3u playlist:
telnet 0 4212
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
Password:
Welcome, Master
> new Test vod enabled
> setup Test input a.m3u
> logout

5) Observe output of the vlc server from start of step 4:

6) Start  vlc client on the same computer, with the same version of vlc
vlc rtsp://127.0.0.1/Test

7) Observe output of the vlc server during the client connect:

8) Observe output of the vlc client (in xterm):

The files b.m3u references exists as well. I have tried both relative and
absolute paths in m3u file, to no avail.

rtsp VOD streaming on single mp3 file works properly.

What is the problem with VOD streaming of playlists??

Is there other way I can stream a playlist with metadata for each song?
