Maybe if you'd post your commands and terminal output we might have a clue as what you are doing.

Now it is clear?

Are you using OpenATV OE build?

Hi SSS,

OpenPLi fixed that, for all receivers it supports. See DEFAULTTUNE = "mips32el-nf".

https://github.com/X...ine/et4x00.conf

Most probably you are using OE-A build https://github.com/o...lude/etxx00.inc, https://github.com/o...ine/et4x00.conf

They can fix it at any time, since they keep their own BSP layer.

[samsamsam]

Hmm how can I check this. Sorry, but I am not familiar to use bb...

[athoik]

OpenPLi does not use buids folder but build folder.

cd /build-enviroment
git remote show origin

Will show information what exacly is cloned under build-environment.

[samsamsam]

* remote origin

  Fetch URL: git://github.com/oe-alliance/build-enviroment.git

  Push  URL: git://github.com/oe-alliance/build-enviroment.git

  HEAD branch: 3.2

  Remote branches:

    1.0  tracked

    2.0  tracked

    2.1  tracked

    2.2  tracked

    2.3  tracked

    3.0  tracked

    3.1  tracked

    3.2  tracked

    next tracked

  Local branch configured for 'git pull':

    3.2 merges with remote 3.2

  Local ref configured for 'git push':

    3.2 pushes to 3.2 (local out of date)

[athoik]

Then ...

git clone https://github.com/OpenPLi/openpli-oe-core /openpli
cd /openpli
make 
MACHINE=et4x00 make image

That will setup your environment and will build image for et4x00.

Then if you have a bitbake that builds your plugin you can build it like this:

cd /openpli/build
source env.source
MACHINE=et4x00 bitbake package-name

[samsamsam]

Thanks. I will try.

 

But as I  mentioned earlier for softfpu I was using custom toolchain prepared using crosstool-ng and sources from the BRC.

 

I will let you know.

SSS

You have to use bitbake to build ffmpeg (eplayer3, ...).

Here is a bitbake for ffmpeg: http://git.yoctoproj...7.12.bb?h=danny

If you want to use just grab ffmpeg_0.7.12.bb and ffmpeg.inc and place them under meta-local/recipes-local/ffmpeg/ffmpeg.inc and meta-local/recipes-local/ffmpeg/ffmpeg_0.7.12.bb

Then if you like to build ffmpeg for et4x00 you do the following:
 

cd build
source env.source
MACHINE=et4x00 bitbake ffmpeg

[samsamsam]

Why I have to build ffmpeg with bb? 

I can build it using my own bash script and only use generated by bb toolchain. 

 

And this configuration: "http://git.yoctoproj...7.12.bb?h=danny" is wrong.

 

Thank you for the help

You have to use bitbake because it makes everything simple and clear. What ever you are doing with your shell script bitbake can do as well even better.

The above bitbake is just a sample to start, you can adjust it based on your parameters.

[samsamsam]

Sorry I do not like bb and I will not use it. 

For my yocto is ....

Every way off build has advantages or disadvantages.

 

But bitbake is in my opinion the best if You build for a stb. (certainly for pli4) .

 

Thank's to a couple off good devs by openpli particularly MiLo which spend a tremendous amount off time to have the base build (linux-core) and basic oe in function off stb correctly compiled versus architecture and cpu.

 

By using bb the build is first configured to the optimum off the targets device. And you squeeze all out off it.

Result is.

Very stable.

Very performant and ussually even low cpu load.

Optimum use off cpu threads.

Optimum use off chipset.

Take also note that for an stb the base dvb drivers are closed source. but the manufacturer will have them compiled with the optimum cpu/arch settings.

If You write an app for that stb and do not use the correct cpu/arch settings you will create self an unstable app.

 

Well bb does that for You.

 

You always can use other ways perhaps you prefer them do know them better but still then You will have to set the wright compile options in function off the stb. (think about the driver).

[MiLo]

Sorry I do not like bb and I will not use it.

You could have saved everyone a lot of time if you just posted that at the beginning. Thank you for wasting our time. Good luck with your project.

[Erik Slagter]

And then not even from our OE...

Probably you understood me wrong. I will use bb from OpenPLI repo to build toolchain (gcc, standard libs, .etc), but I do not know this build system and what I read about  (short recognize about yocto, bb and so on) it is not good for my purpose ...

Many recipes all taken from different repos. Most recipes are unpasteurized, so it add some config option or remove you need add or edit own recipe.

For my purpose I like to have full control on each option.

So, ffmpeg and exteplayer3 purpose for my tests I will build toolchain using generated with bb (a full Compability with other binaries in image, for example standard lib), but themselves I will build with my custom scripts.

I apologize for the misunderstanding.

Thank you. Now it works OK
