fedora18 gmplayer installation

[rholme]

Firstly for the record, fedora 18 comes with gtk, zlib, and alsa installed by default, BUT to configure and build mplayer with the gui interface (hence gmplayer) one needs development versions of include (and possibly libraries). So the following command is necessary BEFORE you "configure --enable-gui"

64 bit:
yum install zlib-devel.x86_64 gtk2-devel.x86_64 alsa-lib-devel.x86_64

for 32 bit, you also need yasm - so
yum install zlib-devel.i686 gtk2-devel.i686 alsa-lib-devel.i686 yasm-devel.i686

The error message from configure is almost worthless (except for yasm) - it mumbles about needing zlib even if it is alsa that is required. The config.log file is worthless for gtk, zlib and alsa as the last line only says checking on the gui.

--- After adding the above I was able to build mplayer and gmplayer successfully.

On the 64 bit machine, all runs fine. On the 32 bit machine mplayer runs fine, but gmplayer brings up a window for graphics for only a split second and then just continues with the audio portion. I logged stuff to see what happened - mostly the same, but ..
gmplayer used a full path to the video while mplayer uses ./

Here is the trailing stuff from mplayer stdout:

Here is the comparable portion from gmplayer stdout:

and stderr from gmplayer also logs

Obviously gmplayer launches mplayer poorly but I have no idea what is being left out of the path or ...

I can live without the graphics version but it sure would be nice to have it working.

PS - I had this working with fedora 16

SMPlayer installs without a hitch and I find it more pleasant.

As for GMPlayer have you read the help first to see how one can launch it?
I could as easy as puting %f on the desktop launcher.

or something else.

Thanks for the info on smplayer - will try it.

As for gmplayer - I can use it fine on the 64 bit machine, it is ONLY the 32 bit that fails (and that is strange as mplayer works there fine). If you do not know, gmplayer is a link to mplayer. I suspect that after determining that the "g" prefix is there that it starts the graphic interface in the parent and launches a child to do the video - and does not setup the environment right for the 32 bit.

moved to Using Fedora from Linux Chat. (seems to be a Fedora-related issue)

You could be right, but that is NOT my first guess.

As mplayer works fine on the 32 bit machine (video + audio) and the gmplayer (parent II suspect) launches the graphical interface forking (again guessing) the window that normally does audio and video BUT THEN THAT child window freaks claiming no video, I suspect it is gmplayer forking a child but not passing the environment along right on the 32 bit version. I noted that using the identical command line (minus the "g" prefix) that the output to stdout/stderr (did not separate) also reflected differing paths to the short movie test I was trying (mplayer uses "./name" and gmplayer uses the fully qualified path.

But I have been wrong before, so you may be right.

OK, THANKS. I removed mplayer - 2d ays installing it gone but good lessons.

SMPLAYER is just what I wanted - total installation - 10 min (finding instructions took a few more).

It does run in debug mode (very verbose) for the 32 bit version. The 64 bit version is fine.
