......snip.....
if (!audio_started) http_req_success = FALSE;
......snip.............
static int failed_tracks = 0;
if (http_req_success) {
failed_tracks = 0;
controller_skip_track ();
} else if (++failed_tracks == 3) {
failed_tracks = 0;
controller_stop_playing ();
controller_show_warning ("Connection error");
} else {
controller_skip_track ();
}
return FALSE;

i'm using the vegalume from the repos.

One of your last changes removed the initialization

call (like manual flash light, or focus control didn't work).
I pushed a new commit for this.

@|ErosizeD|,
there is no configuration file for the video bitrate, but freemangordon
made a change to camera-ui, so it can do higher bitrate.

Am I stupid

. Thanks for that.

BTW as you may probably saw, I wrote a code for bitrate calculation based on video resolution, framerate and quality, but left it commented, as there is no UI to control it and I am not much into GTK to implement one.

Well, that is what i got when run "-DDEBUG" compiled vagalume

The above sequence of messages comes from http.c and has nothing to do with gstreamer, it is curl that fails for some reason. Are you sure after you restore stock codecs vagalume works ok? If that is the case, what exactly do you restore to make it working.

BTW opening the same url with gstreamer0.10-launch works like charm so gstreamer is not broken.

Code:

gst-launch-0.10 playbin2 uri=http://gigue.rrbone.net/310833.ogg2

ok, well it's not working for you either.. so something us 720p folk have has broken it. i wonder could it be kp49? i'll back out the 720p codecs and see if it works then.

edit:backed out codecs,rebooted, and vagalume is still broken, so i guess the codecs themselves are off the hook.. i've no idea what's gone wrong... i don't want to go back to kp48, but might if i can't figure it out..

OH nice, can test with higher bitrates? in my case, 20mbps, in theory higher bitrates, only demands higher write speeds and our nokia N900 its about 8-18mbps so...

If the DPS doesnt limite the bitrate, maybe can get working 20mbps or more, but i think 20 its perfect ( for zero pixelation ).

About the Camera Design, i can help with that

THanks

Seems I've managed to break videocalling, will fix it asap

Now I see, you are cheating! :-)
You disable the whole tracker-process, is it that, why we can get
that high bitrates?
It is a no-go, now it may take minutes until the video is shown
up in media player. We have to find a different way.

I played a bit with dbus-commands for tracker and the indexer.

If you like, please make some tests with this camera-ui-set-priority
file:

Code:

#!/bin/sh
if [ "$1" == "1" ]; then
    run-standalone.sh dbus-send --print-reply --type=method_call --dest=org.freedesktop.Tracker.Indexer /org/freedesktop/Tracker/Indexer org.freedesktop.Tracker.Indexer.Pause
    run-standalone.sh dbus-send --print-reply --type=method_call --dest=org.freedesktop.Tracker /org/freedesktop/Tracker org.freedesktop.Tracker.SetBoolOption string:"Pause" boolean:
    renice 20 `pidof camera-ui`
    renice 20 `pidof Xorg`
    renice 20 `pidof omap3camd`
else
    run-standalone.sh dbus-send --print-reply --type=method_call --dest=org.freedesktop.Tracker.Indexer /org/freedesktop/Tracker/Indexer org.freedesktop.Tracker.Indexer.Continue
    run-standalone.sh dbus-send --print-reply --type=method_call --dest=org.freedesktop.Tracker /org/freedesktop/Tracker org.freedesktop.Tracker.SetBoolOption string:"Pause" boolean:
   renice 0 `pidof camera-ui`
    renice -8 `pidof Xorg`
    renice 0 `pidof omap3camd`
fi

Well, stopping tracker was a quick workaround for its stupidity (trying to index files while camera is recording) until i figure out the correct dbus commands for pause and continue... exactly what you've done. And playing with priorities and other stuff is one of the reason why I made a script instead of hard-coding it in camera-ui. next step will be to move camera-ui in another cgroup while recording,pulling it out from standby tasks cgroup where Nokians in their etheral wisdom had put.

Thanks, will test that, but my expectations are that it will work like charm.

BTW some cheating for time to time won't hurt

Instead of lowering priority it would be easier and better just to create a cgroup for it with low enough cpu.shares (editing /usr/share/policy/etc/current/syspart.conf). No need to move it among cgroups, as long as other process in a better cgroup doesn't need the cpu, it'll get all available cpu resources.
