@SCerovec

Are you interested in Kodi or just OMXPlayer?
I'm still waiting for a reply (contacted privately on E-Mail) from the original Slack x86 Kodi SlackBuild creator. If he's not curious about a collaboration, I might then just do some cosmetic work myself and publish my derived (and butchered) Kodi SlackBuild for ARM (Raspberry Pi). Obviously I'll start a new thread for that.

There is however a small issue with a Kodi dep package that I was not able to compile (someone might be more knowledgeable and do it) - create a tinyXML-2.6.2.so library:
http://www.grinninglizard.com/tinyxml/
https://sourceforge.net/projects/tinyxml/

I have it compiled for both armv6 SF and armv7 HF (extracted from some Debian packages) but I'll need to publish them somewhere for others to be able to download.

@abga,
I'm interested in all maters video acceleration on ARM platforms in the low budget niche:
Rpi
Bpi
Opi
... so far not much luck (Rpi isn't open source hardware, yet has most decent acceleration), but i hope mali/lima comes to mainline soon?

Until then I "throw nets" all over the place in high on hope for an break thru?

@SCerovec

Even if the Rpi VideoCore Broadcom internals are, as you say, closed source, you still can use all of the HW accelerated features with their so called "drivers" from /opt/vc.
http://elinux.org/Raspberry_Pi_VideoCore_APIs
The only issue with running another OS (not Raspbian) on the Pi is that you need to either statically link your multimedia programs to the /opt/vc libs or, do as I do, change the symlinks with the help of some scripts:

cat /kit/glx
#! /bin/sh
cd /usr/lib
rm libEGL.so
ln -s libEGL.so.1.0.0 libEGL.so
rm libGLESv2.so
ln -s libGLESv2.so.2.0.0 libGLESv2.so

cat /kit/glkodi
#! /bin/sh
cd /usr/lib
rm libEGL.so
ln -s /opt/vc/lib/libEGL.so libEGL.so
rm libGLESv2.so
ln -s /opt/vc/lib/libGLESv2.so libGLESv2.so

I do this for Kodi 17.x, because they choose to link it (build scripts) with /usr/lib

Will write a Kodi building HowTo once I'm done with the Slack ARM armv6 HF build.

True,
the compromise Raspberry foundation took, seem to have yielded the soonest solution to any acceleration at all?

It remains to be seen if lima makes it in time to the recent kernels? If I understand correctly, the c.h.i.p. seems to make 4.4.x kernels able to use mali.ko and the binary blob?

So, was trying to build omxplayer on the latest -current and I'm running into the following error:

Code:

gcc is unable to create an executable file.    
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.                     
                                           
If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.                        
make[1]: *** [Makefile.ffmpeg:21: configure] Error 1
make[1]: Leaving directory '/tmp/SBo/omxplayer-git'
make: *** [Makefile:80: ffmpeg] Error 2

Any ideas? I'm still fairly a beginner when it comes to troubleshooting on the ARM platform.

Seems that it's the ffmpeg portion of the script that is failing:

Code:

gcc: error: missing argument to '-mfloat-abi='
C compiler test failed.

Trying to figure out where to insert the -mfloat-abi=hard in the SlackBuild to make it work.

@stormtracknole:
In the Slackbuild script, try changing the lines:

Code:

sed -e '/--enable-cross-compile/d;' \
    -e '/--cross-prefix/d;' \
    -e '/--extra-cflags/ s/-mfpu=vfp //g;' \
    -i Makefile.ffmpeg

to

Code:

sed -e '/--enable-cross-compile/d;' \
    -e '/--cross-prefix/d;' \
    -e '/--extra-cflags/ s/-mfpu=vfp //g;' \
    -e 's/-mfloat-abi=$(FLOAT)//g' \
    -i Makefile.ffmpeg

PERFECT!! That cleared that issue. It's compiling now. Will report back once it's done. Thank you kindly!

Well, it got this far along now:

Code:

Need to satisfy those dependencies (libwebpmux.so.3 and libwebp.so.7) first and see if I'm successful.

slacksam · 10-02-2017, 03:59 PM

@stormtracknole

libwebp from SBo: https://slackbuilds.org/repository/1...aries/libwebp/

Looks like you found a required package I must have overseen.

It did not like 0.5.2, so I'm using libweb-0.6.0. Will report back shortly.

stormtracknole · 10-02-2017, 05:29 PM

SUCCESS!! Using libwebp-0.6.0 and your suggested changes to the SBo script did the trick. Thanks again!

Hi @slacksam! The latest omxplayer.SlackBuild fails to build with the following:

Code:

From https://github.com/popcornmix/omxplayer
 * branch            master     -> FETCH_HEAD
Already up-to-date.
./omxplayer.SlackBuild: line 82: cd: too many arguments

This is a clean download from here. Just an FYI. I did satisfy all the dependencies.

slacksam · 11-14-2017, 01:00 PM

Thanks for reporting.
Now I pushed an update on Github. Please try again.
