Well, next I'd like to forward this issue upstream, but first it must be retested on latest development version of Lucid to make sure the issue still happens there with the latest code. ISO images are available via http://www.ubuntu.com/testing/. If you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system. Also please attach a fresh Xorg.0.log and dmesg from this testing.

I tried playing an MP4 video in the "LiveCD environment" and it asked me to install certain plugins first so I clicked "search" then got this:

"No packages with the requested plugins found"

"The playback of this movie requires a H.264 decoder plugin which is not installed."

I know I'm connected to the internet because that's how I'm making this post :)

Thanks,
Steve

This also occurs on Ubuntu 10.10 "Maverick Meerkat" alpha 3 updated to the latest Totem and GStreamer packages. Playing the video from comment #6 more than once and moving the time slider sometimes results in audio in parts of the movie where there was previously no audio, but then the audio eventually fails while the movie continues to play.

This is still occurring on Ubuntu 12.04 "Precise Pangolin" when playing the video from comment #6.

[madbiologist (me-again)]

When launching the video from comment #6 with gst-launch-0.10 playbin2 uri="file:///$HOME/Downloads/SANY0026.MP4" it displays full-screen (unlike other videos), the problem is still present, and there are several repetitions of:

WARNING: from element /GstPlayBin2:playbin20/GstPlaySink:playsink0/GstBin:vbin/GstAutoVideoSink:videosink/GstXvImageSink:videosink-actual-sink-xvimage: A lot of buffers are being dropped.
Additional debug info:

There may be a timestamping problem, or this computer is too slow.

AMD Athlon XP 2700+ here with ATI R350. Changing affected package to gstreamer.
