totem gstreamer playback judders and is not synced

[Jack Wasey]

play an avi file: totem-gstreamer is poorly synced and judders.
xine on its own plays the movie fine, altough sound sync is still not perfect.
totem-xine plays it the same as xine.

is that with hoary? what audiosink (you can select it with gstreamer-properties)
and soundcard do you use? . Does it do the same with an another audiosink?

I have the same problem with Ubuntu 5.04 AMD64 version. I don't remember what's
the audiosink being used by gstreamer (I'll check when I get back home), but
this happens whether I have the OSS or the ALSA drivers selected in the volumn
control panel. I have a Realtek ALC850 sound chip. I'm using the nVidia
drivers via Synaptic.

I looks like video frames are being dropped at a consistent rate (ie. every x
frame).

My default audiosink in GNOME is ESD.

I am using ubuntu hoary on my notebook and i was having the same problem but the
problem was all gone when I chose alsa as my audio sink rather than esd. I'll
request the bug-incharge (is that the correct terminology?) to try to make sure
that esd is not chosen as the default audiosink for a user in 'future' ubuntu.

Martin, according to Ronald such issues are due to the esdsink and as upstream
recommend to use the alsasink

I know, but we cannot enable alsasink by default in Breezy since dmix still does
not work out of the box for too many sound cards. So esd needs to stay the
default for now until dmix support improves.

However, users are free to change the sink to ALSA theirselves. If it works,
it's certainly preferable to esd.

I added some code to GStreamer-0.8.x esdsink to make video playback acceptably.
It's still not very good, since code such as esd_get_latency() doesn't work (it
hangs; I see similar reports from xine/videolan developers), but at least
video/audio will be somewhat in sync, seeking is ok'ish and video plays
lineairly rather than with hiccups. This should fix most base complaints. Patch
in gst cvs.

Sebastien, could you please apply this patch, so that we have something sensible
for Breezy? Thanks!

Martin, new tarball/version will come this month. Do you want to backport that
or are you ok with waiting for that?

Don't create you even more work than you already have. :-) Fine for me to wait
for the new version.

[Sebastien Bacher (seb128)]

going to do that, thanks :)

[Daniel Holbach (dholbach)]

It was fixed in the upload of gstreamer 0.8.11 - thank you to everybody involved.
