Realplayer Issue
Embedded Realmedia doesn't work with Firefox. The pop-up player opens and keeps loading for ever, but never starts to play.
Path to Realplayer
/usr/local/Realplayer
Open realplayer executable from
/usr/local/bin/realplay
in text editor and edit the following line
"REALPLAYBIN="/usr/bin/aoss $HELIX_LIBS/realplay.bin"
LD_PRELOAD="$LDPRELOAD:/usr/lib/libaoss.so"
export LD_PRELOAD
Then run the command
sh postinst.sh
Choppy audio
I am experiencing choppy audio/video or no audio at all. How do i fix this?
RealPlayer currently uses OSS to output sound to the speakers from the sound card. ALSA is an alternative that does the same job for applications in a slighty better way.
AOSS is a script for OSS emulation through ALSA. You will need to install the RPM for alsa-oss through Yast or from your media if available. Once you've done that, launch RealPlayer using the following syntax
/usr/bin/aoss RealPlayer.
To make this change permanent, open /usr/bin/realplay in your favorite text editor (an example i use is vi)
vi /usr/bin/realplay
Locate the section in the file that has the following line of text:
REALPLAYBIN=$HELIX_LIBS/realplay.bin
and replace it with
REALPLAYBIN="/usr/bin/aoss $HELIX_LIBS/realplay.bin"
Q. How do i uninstall RealPlayer?
Uninstalling an RPM RealPlayer installation:
To uninstall, run the following command as root:
rpm -e RealPlayer
Uninstalling a BIN RealPlayer installation:
To uninstall, download and run the following script: https://player.helixcommunity.org/2005/downloads/uninst.sh
The uninstaller script is currently unsupported. Use it at your own risk.
