Subject:

Wx::Media missing?

I have perl-5.8.8 (built with gcc-4.0.3 on Solaris 8 and RedHat Enterprise Linux 3.0), wx-2.8.2 and Wx-0.70. On both of these UNIX platforms I get this error on the first test: $ perl -Mblib t/01_load.t 1..4 ok 1 - use Wx; Can't locate Wx/Media.pm in @INC (@INC contains: /home/hwadm/.cpan/build/Wx- 0.70/blib/arch /home/hwadm/.cpan/build/Wx- 0.70/blib/lib /opt/perl_5.8.8/lib .) at (eval 20) line 1.

Any idea? Cheers, Marek

For me, under Linux, a missing media library is handled gracefully for both GTK2 and Motif. I really have no idea what might be wrong in your case :-( Mattia

Hmmm - what makes me wonder is that wx-2.8.* does not seem to Include a "media" library any more - it contain "mmedia" Though, but I have no idea whether this is the same or Something completely different... And I see the same test Failure both on Solaris (motif) and Linux (gtk2) here. -Marek Show quoted text

I dived again into this once again, and this is what I found: On Solaris (8, Sparc), when I build wx-2.8.3 (with standard options), I get the following libs: /opt/perl_5.8.8/ext/lib/libwx_base-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_base_net-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_base_xml-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_adv-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_aui-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_core-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_fl-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_gizmos-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_gizmos_xrc-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_gl-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_html-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_media-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_ogl-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_plot-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_qa-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_richtext-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_stc-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_svg-2.8.so@ /opt/perl_5.8.8/ext/lib/libwx_motif_xrc-2.8.so@ As you can see, there is a "libwx_motif_media-2.8.so".

Is there a specific way to test that the "media" interface is OK?

Well, I checked with "nm" and found that in mmedia there is almost only some "Sound" stuff in, while in "media" there "MediaCtrl" in - but why is that not built by wx-2.8.3 on Linux/gtk2? Puzzled, Marek

IIRC in Wx::Demo there is a media example. You can try playing an audio or multimedia file. I used AVI under Win32 and and MP3 under Linux. Show quoted text

mmedia is a completely different (and deprecated) beast. If I remember correctly Wx::MediaCtrl is build if gstreamer 0.8 0r 0.10 is installed (you will also need the -dev packages).

Well, when selecting the Controls->wxMediaCtrl from the demo, I immediately get a segmentation fault :-/ Looks like there _is_ a reason not to support MediaCtrl on Solaris/Motif :-( Show quoted text

Correct, thank you for the hint! This is not transparent at all from the configure run of wx-2.8.3. I installed liboil, libgstreamer and the plugins, and now wx-2.8.3 happily builds libwx_gtk2_media.so and Wx recognizes it (I had to re-install Alien::wxWidgets, though). Now I am trying to build gstreamer on Solaris, and see whether that makes the "media" library on Solaris/Motif work better.. Ah, wait! The MediaCtrl demo in Wx::Demo bombs out on Linux as well (segfault), despite the successful build with gstreamer-0.10 :-( How do you test Wx::Media on Linux? Thanks, Marek

This should work with the correct dependencies. The dependencies are not well documented or managed. They are (as I recall): apt-get -y install libgconf2-dev apt-get -y install libgtk2.0-dev apt-get -y install libgstreamer0.10-0 apt-get -y install libgstreamer0.10-dev apt-get -y install libgstreamer-plugins-base0.10-0 apt-get -y install libgstreamer-plugins-base0.10-dev Then run "cpan -i Wx".
