Title:
Serious video performance regression in cheese
I've confirmed that this is still an issue in Precise.
What happens is that cheese starts recording. Everything is good for
about 5 seconds. Then an icon appears under the main webcam viewing
thing and (I assume) cheese starts transcoding/flushing to disk. At this
point everything gets really

I can *not* confirm that his is fixed. I still have very poor video
performance when recording from my webcam with Oneiric on an HP 625. The
symptoms are the same as in the original description. First, a freeze of
some seconds, and the recorded video is unusable.

If I can integrate Comment #20 and Comment #22, it should fix cheese

Although reducing video frame rate can get acceptable result on Atom
CPUs, it also affects the quality of video recording on other CPUs that
they can get better quality originally.

I don't see this getting fixed for Maverick, though it is a very
unfortunate situation. For natty, we may need to change the system to
first capture video without any encoding, and then encode it after the
fact (rather than do it on the fly as cheese tries to now).

Taking out the videorate and videoscale components both of which should
not be doing anything I don't think (i.e. the rate and resolution from
the camera is fine) makes the video work faster. These elements have
not changed from cheese 2.28.1 indicating a possible GStreamer problem.
Removing
As a comparison I switched out the vorbis/theora codec and replaced it
MP3/MPEG - the performance was even worse.

The update shows the following results on my Dell mini:
At resolution 160x120:
- Pause of about 4s where no video is displayed
- Between 4-7s erratic frame rate
- 7s+ reliable video
At 1280x1024
- Occasionally frame shown (15s per frame)
It seems an improvement on the 14s delay previously seen.
Last night we confirmed this issue and a Dell mini 10v running Lucid as
well as on Maverick. An update to cheese yesterday seems to have
ameliorated the issue on my Maverick Desktop though.

slomo (debian maintainer) said on it that it might be fixed with latest
good release, v4l2src had a bug since many release, that made it prefer
color format conversion over the native format of the camera

the new gstreamer has been uploaded to maverick, I can test the
difference though since cheese has stopped detecting my webcam some days
ago in maverick for some reason, could somebody try with the update?
