Hello,

 

I understand i can't install transcoding in OpenWebif with my hd51

 

(the plugin check /proc/stb/info/model ... )

 

I don't understand why : i have the same cpu than the vu+ solo4k

License payed by Vu+ ? ( the same with raspberry with license ffmpeg )

 

Thank's for your explain

 

 

 

[WanWizard]

Eh... The HD51 has a BCM7251s, the Solo 4K a BCM7376?

 

Quite a different beast... 

[martossien]

Same family armv7ahf-neon

http://www.prnewswir...-223445551.html

Support 4K- 2160p
MPEG-2 / H.264 and H.265 Hardware Decoding
HD HEVC / H.265 2160p60 Main-10 multi-format decoder

[WanWizard]

De CPU is not relevant, it doesn't play any role in processing the transport stream.

 

All previous generation SoC's were MIPSEL CPU's, and still the ET10000 is very different from the DM7000.

[martossien]

Yes hardware soc but im sure the hd51 soc can make transcoding in hardware ( VP9 Capacity fo the 2 soc )

[betacentauri]

Yes, I think hw is capable, but drivers don't support it. So we can't do anything.

[martossien]

Ok i understand, the BCM7251S the dev don't have the source code for hardware video ...
I see 2 other receiver have this ET1000 and HD2400 but don't use the same software (same hardaware )


        try:
            with open("/proc/stb/info/vumodel", "r") as f:
                vumodel = f.readlines();
                vumodel = [x.translate(None, ' \n\r') for x in vumodel]
                vumodel = vumodel[0]
                f.close
        except:
            pass

        try:
            with open("/proc/stb/info/boxtype", "r") as f:
                boxtype = f.readlines();
                boxtype = [x.translate(None, ' \n\r') for x in boxtype]
                boxtype = boxtype[0]
                f.close
        except:
            pass

        if vumodel == "solo2" or vumodel == "duo2" or vumodel == "solose":
            transcoding = "vuplus"
        else:
            if boxtype == "et10000" or boxtype == "hd2400":
                transcoding = "enigma"

        if transcoding == "vuplus":
            port = 8002
        else:
            if transcoding == "enigma2":
        port = 8001

They have the source code (the SDK is the same), but probably not the license. Which is reflected in the price of the box.

 

And without license no support for it in the driver, and no way of accessing the feature.

[Erik Slagter]

Yes, the TS was probably confused by the "if's", but adding the hd51 to this list really won't enable transcoding!

 

What I have heard about the hd51 is that is has limited generic DVB hardware, which can be used e.g. for using PiP ("boxmode 12") but in that case, no capacity is left for transcoding. Maybe it could be possible in "boxmode 1" (no PiP), but Mut@nt hasn't enabled it, for probably a good reason.

 

And to state the obvious again, this has NOTHING to do with the CPU, the CPU of a set-top-box does "nothing".

[martossien]

Merci beaucoup !

Thank's a lot !

 

If i understand :

So the bootloader is give by the builder.

In this bootloader , the builder give some api for the os to use the hardware of the stb.

For exemple Mutant (v1.07-r19r) give 2 mode 1 "boxmode 1" and second "boxmode 12" . The second give PiP Up to 1/2 x 1/2 screen display, 576i50.

But not the transcoding hardware function in this 2 mode.

 

The little dual core arm7 can't make the transcoding only in software mode

 

Openpli give the choice to use the "boxmode 12" ?

 

Do openpli use the 1.7 Ghz speed of this new bootloader ?

 

I have installed ( thank's for the help of this forum ) the IPTV Player and with some vidoo flux it use 20 % of cpu ( /usr/bin/gstplayer ) and i try some vlc

So i understand it's only decompression and for compression FFMPEG use more cpu.

i have a look i find some nas make transcoding with dual core 1.4 ghz armv7:

212 ARMv7 ARMv7 1.4Ghz Quad Core Yes Yes Yes Yes Yes Real-time transcoding locked to 480p

 

So can i make so test ( with vlc or other ) to check if this cpu can make a small transcode video flux in software compression ( mpeg2 to 360p H264 sound mono 11Khz) ?

[martossien]

where i can find a binary ffmpeg for my hd51 ?

i test

http://iptvplayer.pl...in/armv7/ffmpeg

but it don't work on my receiver.

[Erik Slagter]

It's in the feeds, just type "opkg install ffmpeg".

[martossien]

not in hd51 :

root@hd51:/# opkg install ffmpeg
Unknown package 'ffmpeg'.
Collected errors:
 * opkg_install_cmd: Cannot install package ffmpeg.

strange - vs1500 (same as hd51):

Yeah. In that case, hold on tight until the next release.
