Hey,

I would like to build a minimal vlc to just play a h264 RTP stream. I'm using vlc-2.2 from git (4f12d2a2fd664c63da5cbd60f264167521a926d3). I configure with pretty much everything disabled. I enabled:

Code: Select all

--enable-live555
--enable-avcodec
--enable-swscale
--enable-xcb

When installing these dependencies from my distribution (kubuntu 16.04) everything works as expected.
My next step is to use my own version of live555. I built live555 with

Code: Select all

./genMakefiles linux
make
DESTDIR="/home/devel/live555/install" make install

To point vlc to use my own version I called configure with:

Code: Select all

--with-contrib=/home/devel/live555/install/usr/local

.
When I run ./configure it says that live555 is not present:

Code: Select all

checking for LIVE555... no
configure: WARNING: No package 'live555' found.
checking for live555 version 1324598400 or later... no
configure: WARNING: live555 is missing or its installed version is too old:
Version 2011.12.23 or later is required to proceed.
You can get an updated one from http://www.live555.com/liveMedia .
configure: error: Update live555 or pass --disable-live555 to disable RTSP input support.

I think I figured out why. configure.ac, line 1612:

Code: Select all

AS_IF([test -f "${CONTRIB_DIR}/include/UsageEnvironment.hh"], [

But the file UsageEnvironment.hh is located in another subfolder UsageEnvironment:

Code: Select all

${CONTRIB_DIR}/include/UsageEnvironment/UsageEnvironment.hh

When I change this, the output of ./configure is:

Code: Select all

checking for LIVE555... no
configure: WARNING: No package 'live555' found.
checking for live555 version 1324598400 or later... yes
checking for main in -lliveMedia_pic... no
checking for main in -lliveMedia... yes

I'm not sure if this is OK? Anyway, my application won't play the stream.

There are two questions:
1 Is this a bug in configure.ac?
2 What do I need to do to successfully build libvlc with my own copy of live555 library?

Kind Regards,
Simon

It means you don't have the live555.pc file, so configure went through the legacy fallback for live555 detection. It's not an issue.

Thank you for your fast reply. Using the contrib-method for live555 ./configure shows the same message:

Code: Select all

checking for LIVE555... no
configure: WARNING: No package 'live555' found.
checking for live555 version 1324598400 or later... yes
checking for main in -lliveMedia_pic... no
checking for main in -lliveMedia... yes

And, again, no stream receive is possible. Do you have any idea? live555 is supposed to be statically linked to a vlc plugin (access/liblive555_plugin.so) using this method, right?

The first questions is answered, the second is not. I learned that either I need to use my distrubutors version or use the "contrib-method": https://wiki.videolan.org/UnixCompile#T ... .22_method

Cheers,
Simon

I think you have answered the second question yourself, is all.

Well, yes. Building libvlc was successful.
Then another question arises: Why isn't working? And what do I have to do to get it working?

Posted: **18 Aug 2016 18:04**

I can't answer that question. Look at the logs, traces, debugger...

Thank you for your replies. Unsurprisingly it was my mistake. IP-Addresses have been wrong.
Cheers Simon
