GNOME Bugzilla – Bug 752318
Image jitter and no sound when streaming H.264
Last modified: 2016-04-15 13:50:19 UTC
(Please bear with me as I am close to new to this and I do not even know whether this IS a bug.) Environment: Ubuntu 14.04.2 with kernel 3.16.0-43-generic on x86_64 Intel duo core Install: totem 3.10.1-1ubuntu4 with all optional add-ons from USC. gstreamer0.10-plugins-bad-multiverse 0.10.21-1ubuntu3 gstreamer0.10-plugins-bad 0.10.23-7.2ubuntu1.1 gstreamer0.10-plugins-ugly 0.10.19-2ubuntu5 I have seen bugs 482660 and 728655. Both seems somewhat related to what follows. As I stream: http://delive.artestras.cshls.lldns.net/artestras/delive/delive/delive_925.m3u8 I first get approx 5s of perfect image and sound followed by frozen image and zero sound. The image may later thaw every 15 seconds or so, jumps and freezes again immediately. Sound does not come back. Stopping the stream and restarting it, causes the exact same thing to happen again. No problem whatsoever with VLC using H264-MPEG-4 AVC (part10) for either sound or video signal. I am ready to help with debugging or whatever, if properly coached. Thank you.
COMMENT #1: As suggested in Bug 728655 I tried: > gst-play-1.0 http://delive.artestras.cshls.lldns.net/artestras/delive/delive/delive_925.m3u8 It works like a charm. So to recap: VLC works perfectly and so does gstreamer with no GUI. Does that point to totem as the trouble-maker ?
Bug 750808 again? (You'll probably want to upgrade from the 1.5 year-old versions in your distribution).
Thanks Bastien, Do you mean that I ought to upgrade from the current drivers for my GPU chipset as suggested at the end of bug 750808 ? Or something else ? Can you be more specific ? If that's it (which somehow I doubt) I am using X.Org X server from xserver-xorg-video-nouveau for my NVIDIA G84GLM [Quadro FX 570M]. It is up to date. If you are talking about the 3.10.1 version of the totem package I have installed, I am basically using what's on Ubuntu Soft Center. I just imagined it was in sync with my kernel version and thought nothing of it. I usually upgrade only when I need a new feature, not because I want the shiniest and latest. I usually don't. So let me know what you meant. Why and what do you think I should upgrade ?
@Bastien_Nocera: If I try opening `totem 3.14.2-0ubuntu1~ppa1` with USC from the page: http://www.ubuntuupdates.org/package/ubuntu-desktop_ppa/vivid/main/base/totem I get: Error: Breaks existing package 'totem-mozilla' dependency (=3.10.1-1ubuntu4) which is along the line of what I expected. I am sure you have seen that a zillion times. Was that what you meant me to do ? If totem 3.10 is still supported, I would rather go that route and stick to Tusty 14.04.2 LTS.
Never mind comment 2, I skipped over the bug content, and went from the bug title. Looks line a problem parsing the playlist.
ok. One thing less to worry about. So where do I go from here ? I am sure I am not the only one to experience this particular problem. Can someone offer advice on how to trouleshoot this ?
