Edit audio/video buffer size?

29 November 2015 - 15:00

Is there some way to change the audio and video buffer size in Enigma2 ?
It is the dvb live tv buffers that I would like to edit not the Gstreamer buffers.
Is it even possible? Or is it completly hardware/driver based?

The reason I would like to edit this is because I think this could perhaps solve my audio dropouts on channels with aac-he audio.

Cool TV Guide 1920x1080 full screen skin V2.

10 September 2015 - 20:03

With complete respect to Eragon who began to modify the skin as in this thread: http://www.vuplus-co...0-x-1080.23427/
 
I was also bothered with the skin not working full screen for our VU+ boxes, and it seems that the developer has stoped updating Cool Tv Guide..
 
With inspiration from Eragon I took all of the screens from the Cool TV guide and rezised them. (Eragon I did not use any of your files). 
 
The method is the same as described in Eragons thread.
 
Use any FTP program and upload the following files to :
/usr/lib/enigma2/python/Plugins/Extensions/CoolTVGuide/CoolSkin
 
CoolChannelGuide_1280.xml
CoolChannelGuide2_1280.xml
CoolChannelGuide3_1280.xml
CoolEasyGuide_1280.xml
CoolEasyGuide2_1280.xml
CoolEasyGuide3_1280.xml
CoolInfoGuide_1280.xml
CoolMultiGuide_1280.xml
CoolNiceGuide_1280.xml
CoolSearch_1280.xml
CoolSingleGuide_1280.xml
CoolSingleGuide2_1280.xml
CoolSingleGuide3_1280.xml
CoolTinyGuide_1280.xml
CoolTVGuide_1280.xml
CoolTVGuideSetup.xml
 
(All of the above files are included in the Coolskin2.zip)
 
Then you need to upload the following new graphics from file "Cool3d.zip" to:
/usr/lib/enigma2/python/Plugins/Extensions/CoolTVGuide/Cool3D/Menu
 
CoolChannelGuide.png
CoolEasyGuide.png
CoolEasyGuide2.png
CoolFrame.png
CoolFrame2.png
CoolMultiGuide.png
CoolSingleGuide.png
CoolTVGuide.png
 
And also these new graphics to:
/usr/lib/enigma2/python/Plugins/Extensions/CoolTVGuide/Cool3D
 
CoolCursor.png
CoolCursor2.png
progress.png
progress_back.png
timeline-now.png
 
Afterwards make sure that all new files is set to Permission 644.
Reebot and enjoy fullscreen Cool TV Guide!.
 
Report back problems with graphics.

Bug found in DVB-T2

20 August 2015 - 11:32

Hello.
 

I found a bug in the DVB-T2 section that is very important to fix.

 

The bug is missing values when scanning DVB-T2 networks.

 
I can scan all the Swedish muxes except for this one:
MUX 7 UHF 730 MHz channel 53 32KE, 256 QAM, PP4, 3/5, Guard 19/256, 32,49 Mbit/s, DVB-T2
 
This mux works fine: MUX 6 UHF 618 MHz channel 39 32KE, 256 QAM, PP4, 2/3, Guard 1/16, 36,55 Mbit/s, DVB-T2
 
If you look at the code : https://github.com/o...terrestrial.xml
 
You can see this part:
 
code_rate_{lp,hp}:
0 = 1/2,
1 = 2/3,
2 = 3/4,
3 = 5/6,
4 = 7/8,
5 = Auto (default),
6 = None
 
And the code_rate option 3/5 is missing and also 4/5, The missing code rate 3/5 is probably why I can not scan this mux.
 
 
DVB-T has (1/2, 2/3, 3/4, 5/6, 7/8) DVB-T2 has (1/2, 3/5, 2/3, 3/4, 4/5)
 

 

 

This have been found on openpli before but not fixed: http://forums.openpl...ication-needed/
 
Here is also the source for openpli and on line 975 in ScanSetup.py the "Terrestial" section is missing the Code rate 3/5 and also 4/5.
 
    # terrestial
        self.scan_ter.frequency = ConfigInteger(default = defaultTer["frequency"], limits = (50000, 999000))
        self.scan_ter.channel = ConfigInteger(default = 21, limits = (1, 99))
        self.scan_ter.inversion = ConfigSelection(default = defaultTer["inversion"], choices = [
            (eDVBFrontendParametersTerrestrial.Inversion_Off, _("Off")),
            (eDVBFrontendParametersTerrestrial.Inversion_On, _("On")),
            (eDVBFrontendParametersTerrestrial.Inversion_Unknown, _("Auto"))])
        # WORKAROUND: we can't use BW-auto
        self.scan_ter.bandwidth = ConfigSelection(default = defaultTer["bandwidth"], choices = [

            ])
        #, (eDVBFrontendParametersTerrestrial.Bandwidth_Auto, _("Auto"))))
        self.scan_ter.fechigh = ConfigSelection(default = defaultTer["fechigh"], choices = [
            (eDVBFrontendParametersTerrestrial.FEC_1_2, "1/2"),

            (eDVBFrontendParametersTerrestrial.FEC_3_4, "3/4"),
            (eDVBFrontendParametersTerrestrial.FEC_5_6, "5/6"),
            (eDVBFrontendParametersTerrestrial.FEC_6_7, "6/7"),
            (eDVBFrontendParametersTerrestrial.FEC_7_8, "7/8"),
            (eDVBFrontendParametersTerrestrial.FEC_8_9, "8/9"),
            (eDVBFrontendParametersTerrestrial.FEC_Auto, _("Auto"))])
        self.scan_ter.feclow = ConfigSelection(default = defaultTer["feclow"], choices = [
            (eDVBFrontendParametersTerrestrial.FEC_1_2, "1/2"),
            (eDVBFrontendParametersTerrestrial.FEC_2_3, "2/3"),
            (eDVBFrontendParametersTerrestrial.FEC_3_4, "3/4"),

            (eDVBFrontendParametersTerrestrial.FEC_8_9, "8/9"),
            (eDVBFrontendParametersTerrestrial.FEC_Auto, _("Auto"))])
 
The same is found in the transponder.py  : http://sourceforge.n.../Transponder.py
 
    elif type == "DVB-T":
        ret["tuner_type"] = _("Terrestrial")
        ret["bandwidth"] = {
            0 : _("Auto"),
            10000000 : "10 MHz",
            8000000 : "8 MHz",
            7000000 : "7 MHz",
            6000000 : "6 MHz",
            5000000 : "5 MHz",
            1712000 : "1.712 MHz"}.get(tp.get("bandwidth"))
        ret["code_rate_lp"] = {
            eDVBFrontendParametersTerrestrial.FEC_Auto : _("Auto"),
            eDVBFrontendParametersTerrestrial.FEC_1_2 : "1/2",
            eDVBFrontendParametersTerrestrial.FEC_2_3 : "2/3",
            eDVBFrontendParametersTerrestrial.FEC_3_4 : "3/4",
            eDVBFrontendParametersTerrestrial.FEC_5_6 : "5/6",
            eDVBFrontendParametersTerrestrial.FEC_6_7 : "6/7",
            eDVBFrontendParametersTerrestrial.FEC_7_8 : "7/8",
            eDVBFrontendParametersTerrestrial.FEC_8_9 : "8/9"}.get(tp.get("code_rate_lp"))
        ret["code_rate_hp"] = {
            eDVBFrontendParametersTerrestrial.FEC_Auto : _("Auto"),
            eDVBFrontendParametersTerrestrial.FEC_1_2 : "1/2",
            eDVBFrontendParametersTerrestrial.FEC_2_3 : "2/3",
            eDVBFrontendParametersTerrestrial.FEC_3_4 : "3/4",
            eDVBFrontendParametersTerrestrial.FEC_5_6 : "5/6",
            eDVBFrontendParametersTerrestrial.FEC_6_7 : "6/7",
            eDVBFrontendParametersTerrestrial.FEC_7_8 : "7/8",
            eDVBFrontendParametersTerrestrial.FEC_8_9 : "8/9"}.get(tp.get("code_rate_hp"))
        
        
If you look at the "Sat" and "Cable" part of the code they have the correct FEC 3/5 and 4/5.
I am not a coder so I need help regarding to solve this issue. As long as this is not fixed, the DVB-T2 part of Enigma2 is not working 100%
