Hi,
Yesterday I was doing a couple of test of memory consumption..

http://code.google.com/p/dissonance/wik … ersPlayers

Let each one draw their own conclusions.
... and every opinion is welcome.

Regards.

ps: After 4 months (Woow.. too much), the next weekend release Pragha 1.0 and 0.8.11RC

Nice comparison! How about testing "Goggles Music Manager" (gogglesmm in community) as well?

It was a very unscientific comparison

I think a better method would be to do the memory test individually, instead of opening all the applications together. Also, don't have any other unnecessary application running, such as soffice.bin etc.

+1

msdelos · 2012-01-26 00:54:58

Yes GogglesGuy..
Some time want to test gogglesmm, but can not find fox packages for fedora. I'll try to compile by hand.

It was a very unscientific comparison?? Yesss...
Wanted to do it only for compare consonance with pragha, and finally add the rest.. haha..

I found more interesting to watch all the players at the same time, to avoid differences for different uses of cpu, mem, in the system.

About the rest of the applications, on the contrary, I saw very interesting.
Justly LibreOffice Writer that occupying only 88 MB (Verified with xfce4-taskmanager), weighs less than many players and is on par with pragha, it is very curious. It seems that the guys from Libreoffice, did very well.. No?.

The biggest problem with these comparisons are the libraries/services used by applications on desktops strangers, but this script shows the results of the memory used by each program, regardless of libraries/services used.

Thus, for example looking the case of amarok, then display only the consumption of the application, but charge amarok on xfce involves loading kde4d, kio_http, kio_file, etc etc. .. but also, using amarok on kde, will consume the same 300mb used in xfce independently of the graphical environment used. Corroborated.

Regards.

p.s:. I also like to make an analysis of the consumption of cpu, etc, but is much more relative. This comparison is simple, but very real.

msdelos · 2012-02-02 04:18:36

Hi,

Well.. Two little things.

First:
Tested gogglesmm, and the result is:

 Private  +   Shared  =  RAM used	Program 
 6.7 MiB + 544.0 KiB =   7.2 MiB	gogglesmm (When open)
19.2 MiB + 527.0 KiB =  19.7 MiB	gogglesmm (Analized library)
22.1 MiB +   1.7 MiB =  23.8 MiB	gogglesmm (Playing a track)

Congratulations GogglesGuy. Is an excellent player and will take a couple of ideas for pragha.

Second:
Finally .. and after 4 months.. Pragha 1.0.

Full Changelog and tarball here: http://code.google.com/p/dissonance/dow … .0.tar.bz2

Tomorrow make a bit more promotion.
Good night.

When I set alsa device 'hdsp' a playing back still takes place through default (hda pulse) device. At next configuration dialog opening device string is empty.

2. Can you, please, describe current player state in relation with these two competitor's issues (one of last ones is fixed):

http://code.google.com/p/clementine-pla … il?id=2111
http://code.google.com/p/clementine-pla … il?id=2114

These issues are common for almost all players, and I hope it isn't offensive I have placed these links here, is it?

Hi student975,

All comments are always welcome.

First of all.
Which player are using?. Pragha 0.8.*/Consonance or Pragha 1.0?

About 1:
How select hdsp?
I think that both pragha as consonance only support hardware addresses like "hw:1,0"

Here a good explanation of how to do it: http://superuser.com/a/53977

If you use Pragha 1.0, other way, more easy is select the device with gstreamer-properties, and set default in Pragha.

About first link, I prefer linear volume. if you compile with GSTREAMER_PLUGINS_BASE, set linear volume by default, On the contrary is cubic volume and therefore in db. No? I have to investigate it. Thanks for the link,

About the second link, later see it properly.

Regards.

student975 · 2012-03-13 17:15:57

msdelos,

- I'm using official arch pragha package: community/pragha 1.0-2.
- It is impossible to select needed device using 'hw' as far as the device is dmix-based.
- I haven't gstreamer-properties (and gnome) installed, and, at any case, I use different (three) cards for different purposes, and basing on default device isn't acceptable. And, as far as I know, gst hasn't any problems dealing with alsa (symbolic) devices.
- Linear volume == exponential amplitude. It is an unbreakable human hearing law. Not cubic, not any other function In fact that GstEnginePipeline::UpdateVolume() function is sufficient as leading rule (transforms percent of volume to hardware volume where last one has range from 0.0 to 1.0).

Apology. I am investigating, but apparently not. symbolic devices should work but seems that dmix is another case. See here a bug example: https://bugzilla.gnome.org/show_bug.cgi?id=325780
According to the gstreamer documentation, the "device" property of alsasink is the ALSA device, as defined in an asound configuration file, and the default value is "default", but do not find any reference to dmix. Also alsadmixsink suggested in the bug not exists.

Ok. I had doubts but you are right.
Test change any reference of GST_STREAM_VOLUME_FORMAT_CUBIC to GST_STREAM_VOLUME_FORMAT_DB in pragha-bancked.c and it should work ..

I will continue investigating tomorrow.

Matias.

student975 · 2012-03-15 05:31:37

I have wrote "dmix-based". My /etc/asound.conf has this fragment:

pcm.hdspDmixer { 
    type dmix 
    ipc_key 1024
    ipc_key_add_uid false
    ipc_perm 0666
    slave { 
        pcm "hw:1,0" 
        period_time 0 
        period_size 1024 
        buffer_size 8192
        rate 44100
        format "S32_LE"
        channels 12
    }
    bindings { 
        0 10
        1 11
        10 0
        11 1
    } 
    hint {
      show on
      description "hdspDmixer"
    }
} 

ctl.hdspDmixer { 
    type hw 
    card 1 
}

pcm.hdsp { 
    type plug 
    slave.pcm "hdspDmixer" 
    hint {
      show on
      description "hdsp"
    }
}

You see, "end-user" device here is 'hdsp'. All software (as well as also gst-based clementine) sees (and works with) this device without problems. 'aplay -L' just list available alsa devices - and ones defined in asound.conf (and in ~/.asoundrc) also.

As for volume, I wouldn't trust any external (gstreamer's here) imagination about correctness and would use own transformation (similar to that function - it's just few strings) using linear volume library interface.

msdelos · 2012-03-15 12:12:08

I'm honest?
You're the first person you want to use this!.

Well, You could compile from git?.

Now write a small patch. if you say that clementine work, pragha also should work!.

And please, test run "pragha -e 1" in a terminal, and comment any warning here.

Regards.

Edit: Test.

git clone git://github.com/matiasdelellis/pragha.git
cd pragha
./autogen.sh

Here see that return "Cubic volume support...............(Need gstreamer-plugins-base-devel).: Yes", to have "linear volume". Yes. I know. is not linear volume but is a good approximation.

make
./src/pragha -e 1

Thanks, I have tried git version on the place. Setting device does work (say, it does work via mentioned hdsp device), but config dialog doesn't show current configured device (while the device is written into ~/.config/pragha/config): next dialog opening has empty device field.

msdelos wrote:

Sorry, I don't understand why we need approximation at situation when direct following to the law costs nothing (just five or so strings of code). Why we need to answer to "1 + 1 = ?" question as 1.8 or 2.3 instead of 2?

msdelos · 2012-03-15 17:24:05

Thanks to you.
As it is a feature that does not use, never I realized the error. Now in git also fix the preferences dialog.

Well..
Regarding the volumes now I'm confused.

In the Playbin2 (The heart of pragha) documentation.
The "volume" property say: Get or set the current audio stream volume. 1.0 means 100%, 0.0 means mute. This uses a linear volume scale.

Also in GstStreamVolume doc say:
This volume is always a linear factor, i.e. 0.0 is muted 1.0 is 100%. For showing the volume in a GUI it might make sense to convert it to a different format by using gst_stream_volume_convert_volume(). Volume sliders should usually use a cubic volume.

The gtk_volume_button_new widget (Used in pragha) not show any reference to the scale used, but I assumed it was cubic, and made the conversion. in the same way that rhyntombox and totem for example.

Test

git pull
./autogen.sh --disable-gstreamer-plugins-base-0.10
make

When you compiling obviate the conversion.

student975 · 2012-03-15 17:35:10

Yes, config dialog is fixed now, thank!

As for the volume settings. Don't use any converters form gst or any other. Use those 5 lines of code. Say, volume slider has 0-100 (integer) range. Than that conversion just works (volume_percent_ must be replaced with your slider value, vol is converted result in 0.0..1.0 range to use in setting volume via gst API).

msdelos · 2012-03-16 02:01:28

Well.. But compiling with ./autogen.sh --disxable-gstreamer-plugins-base-0.10 & make, works as expected?

When disable gstreamer-plugins-base-0.10, pragha apply the volume directly, without converting any value.

0 < Value slider < 100
So, set volume like: (Value slider / 100) = (0.0 < volume < 1.0)

mm..
It's late. Tomorrow continue investigating what is wrong..

Regards.

Well.. But compiling with ./autogen.sh --disxable-gstreamer-plugins-base-0.10 & make, works as expected?

Yes, incorrectly as expected!! Slider's middle corresponds to -6db. So all we need now is to replace (volume_slider / 100.0) with few strings with exponent, something like

  float vol = 0.0;
  if (slider_percent <= 0)
    vol = 0.0;
  else if (slider_percent >= 100)
    vol = 1.0;
  else {
    float db = float(slider_percent - 100) / 2.0;
    vol = pow(10.0, db / 20.0);
  }
  // use vol here

After that it would be possible to change mouse wheel step from (as I think) 4 percents to 1 or (probably more handy) 2 percents. As a result, the same percents changing will be the same for our ears at any volume point.
