First of all thanks Remi Denis for your reply and I absolutely agree with
your reply in case of stream is delivered through RTP/RTCP protocol. I am
sorry that I forgot to mention the protocol that I used to deliver the media
and it is: I am using MPEG-2 Transport Stream in which there is no concept
of RTCP so, there is no way to announce the EOF reached event to the client
and client is still waiting for the data instead of sending TEARDOWN. I feel
in such cases server need to ANNOUNCE EOF event to the client so that it
will teardown the RTSP session. Another doubt that I had is how I can add
another RTSP method to server? Which files and area of code that I need to
modify. Once what happened is I have added PING method to the server in
misc/rtsp.c file which has given me core dump. Another thing which I didn't
understand is that why the two functions named "RtspCallback" and "
RtspCallbackES" were present as it seems that both were implemented the same
functionality?

Hi,
I have transcoded a file using x264. The resultant, transcoded file is not
giving timestamp while playing. I have ingested that file into VLC
streamming server through command line. As its duration is not retrieved the
SDP doesn't contain the duration of the video so that at the end of the file
client can send the TEARDOWN. So, now the problem is: The EOF (end of file)
event is occurring at server end and client is not known about that and it's
still expecting rtp data. But, at the server end the EOF is occurred and
RTSP session is still alive and there is flow of media data. To resolve this
problem I want to ANNOUNCE about the EOF event to the client so that it will
send TEARDOWN to the server and the RTSP session can be stopped.
Can, anyone help me how I can know about the EOF event in
modules/misc/rtsp.c file for that particular session? and
How can I send a ANNOUNCE message to the client?
Thanks & Regards,
Ravinder

Hi,
I have started VLC in vod server mode. I have ingested few video files with
few labels. I want to delete some particular label from the server but,
before deleting the label I want to check whether any rtsp sessions are
established and running on that label or not from network module, httpd.c
file of the vlc. Can any one help me to do this. First of all whether it is
possible to know the above asked information in httpd.c or not if yes, then
which function I need to call to know the status of the label?
Thanks & Regards,
Ravinder

The TEARDOWN should occur as a consequence of the server sending an RTCP
BYE compound for each medias. There is no need to advertise the duration of
the session for this to work. In fact, sometimes even the server does not
know the length.
It is very likely that misc/rtsp.c fails to send a BYE compound since it is
very low-quality code.

Hi, I just wanted to report a bug I encountered with the Mac OSX
version of VLC.
When I used "Check for Update" to update to version 1.0 from the
pervious version I had (0.9 something, it was the last version before
1.0), version 1.0 didn't show up under "Check for Update."
I only happened to find out about the update from somebody I follow n
Twitter. Straight away I opened VLC, & selected "Check for Update",
but to no avail. So I had to manually download it from the website. I
would very much like for this bug to be fixed, as I still probably
wouldn't know about the update without Twitter.
Love the app!
Thank you.

Hola. He tratado de usar la caracter?stica "Compensar desincronizaci?n de

y borr? las preferencias anteriores usando el script que viene en el
instalador, pero sin resultados. Les agradezco que solucionen este problema.
Gracias

I'm slightly confused by the installer for VLC 1.0.0 Win32. It seems to be
set up based on a misinterpretation of the GPL. The installer says "You must
accept the agreement to install VLC media player", with the GPL version 2
being presented as the agreement, but section 0 of the GPL says "Activities
other than copying, distribution and modification are not covered by this
License; they are outside its scope.". A quick search for the word "agree"
shows no references to the reader agreeing to anything. If the license
doesn't place any conditions on using the program, why does the user have to
accept it?
Also, section 6 says "You are not responsible for enforcing compliance by
third parties to this License.", which the installer seems to be an attempt
to do. Depending on how the GPL is interpreted, this might actually be a
violation of section 4's "You may not...sublicense...the Program", or
section 6's "You may not impose any further restrictions on the recipients'
exercise of the rights ranted herein.". IANAL.
Note the installers of 7-Zip, Ghostscript and PowerIso, which simply install
the program and include the GPL as a text file in the installed folder. I
can't check Pidgin and Firefox because I have them already installed, but I
think they work similarly, or at most give the user the opportunity to
review the GPL before installation without requiring them to read or agree
to it.
