GStreamer | don't know | Ver: 0.10.14
Summary: Gstreamer streaming buffer too small for large videos
Product: GStreamer
Version: 0.10.14
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: don't know
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: dnas.dnas at gmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.19/2.20
GNOME milestone: Unspecified
Please describe the problem:
Gstreamer should have more accurate heuristics on how much to buffer when
streaming video. The current setup works extremely poorly for large videos.
Steps to reproduce:
1. Go to http://www.apple.com/trailers/
2. Pick a trailer available in HD. (For example, WALL-E).
3. Select the highest size available (1080p)
4. Watch video
Actual results:
Every 5-20 seconds, play stops to fill the buffer again. This is annoying and
makes the video more-or-less unwatchable.
Expected results:
After buffering some initial amount, the video plays with little or no stops
for further buffering.
Does this happen every time?
Yes.
Other information:
(I have the totem-mozilla plugin, as packaged by Ubuntu Gutsy Gibbon. I assume
that is needed to get the video to launch nicely.)
Perhaps gstreamer should take into account the current average download speed
(a moving average?) and how much data is needed for one second of playback, and
use that to calculate the needed buffer size.
