To: [email protected], [email protected], Discussion of the development of and with GStreamer <[email protected]> Hi all. I have been banging my head for over 5 days now; went through whatever google-literature I could possibly through. But I guess I will have to ask the experts :| I will list down my queries with the story regarding that query, so as to maintain modularity as far as possible. I have a x86-based Fedora-14 Dell laptop; and a XO-1. A) On my Dell laptop, the following work seamlessly, and I am able to enjoy the mp3. (i) gst-launch filesrc location=/path/to/mp3 ! mad ! alsasink (ii) gst-launch filesrc location=/path/to/mp3 ! mad ! pulsesink However, on my XO-1, only the following works :: (i) gst-launch filesrc location=/path/to/mp3 ! mad ! alsasink whereas the following shows the "pulsesink" plugin not found error :: (ii) gst-launch filesrc location=/path/to/mp3 ! mad ! pulsesink I figured out that the package "gstreamer-plugins-good" is required for the "pulsesink" plugin. So, I did "gst-inspect" on both machines, and "rpm -qa | grep gstreamer-plugins-good" on both the machines. To my horror, I saw that the package "gstreamer-plugins-good-0.10.26-1.fc14.i686" was installed on both the Dell machine, and the XO-1, but only the Dell laptop showed the presence of "pulsesink". Why could this difference be ? B) Anyhow, I copied "libgstpulse.so" from my Dell machine to the XO-1. Thereafter, "pulsesink" could be recognised on the XO-1. However, "gst-launch filesrc location=/path/to/mp3 ! mad ! pulsesink" resulted in a sound only on Dell, and not XO-1. So, I researched further, and concluded that I needed to install "alsa-plugins-pulseaudio" on the XO-1, so as to set up the pulseaudio server, and have the alsa-device as the "other end of the pulseaudio proxy". So, I installed the package. However, SOUND HAS STOPPED PLAYING COMPLETELY ON THE XO-1 (the only time I hear some sound is during boot-up time). If I remove "alsa-plugins-pulseaudio", I can again hear the sound via "alsasink", but not through "pulsesink". If I re-install "alsa-plugins-pulseaudio", I can not hear sound through "alsasink", nor "pulsesink", ( not even after doing the following steps :: pulsesudio --kill sudo rm -r ~/.pulse sudo rm -r ~/.pulse-cookie pulseaudio --start <trying to run the mp3 with sudo previleges.> ) So, what other thing could I possibly do? Will be grateful for a reply. Thanks and Regards, Ajay
