Compile ffmpeg with hardware decoding for Odroid C2

[fretzke]

Hi everyone,

so I was trying to build ffmpeg with enabled hardware decoder for the C2 based on serveral posts scattered around the web. In the beginning everything looked quite promising, but now I keep running into one problem that I cannot seem to solve.

Hence two questions to you all:

1. • Did anyone succeed in compiling ffmpeg for the C2?

• Any ideas how to get over this error?

Here's what I did so far:

Install serveral a/v libraries required by ffmpeg

Code: Select all

apt-get install mercurial libfaac-dev libmp3lame-dev libopus-dev libtheora-dev libvorbis-dev libfreetype6-dev libx264-dev libasound2-dev

Build the AML libs

Code: Select all

git clone https://github.com/Owersun/c2_aml_libs.git
cd c2_aml_libs
make all -j4
make install
cd ..

Build x265 lib

Code: Select all

hg clone https://bitbucket.org/multicoreware/x265
cd x265/build/linux
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="/temp/ffmpeg_build"  -DENABLE_SHARED:bool=off ../../source
make -j4
make install
cd ../..

Build ffmpeg branch for AML VPU

Code: Select all

git clone git://github.com/LongChair/FFmpeg
cd FFmpeg
CFLAGS='-L/temp/c2_aml_libs/amcodec:-I/temp/c2_aml_libs/amcodec/include' PKG_CONFIG_PATH="/temp/ffmpeg_build/lib/pkgconfig" ./configure --pkg-config-flags="--static" --enable-gpl --enable-libass --enable-libfaac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libx265 --enable-nonfree --enable-aml --enable-decoder=h264_aml --enable-decoder=hevc_aml --enable-decoder=mpeg2_aml --enable-decoder=mpeg4_aml --enable-decoder=mpeg4v1_aml --enable-decoder=mpeg4v2_aml --enable-decoder=mpeg4v3_aml --enable-decoder=vc1_aml
make -j4

This throws:

Code: Select all

ERROR : amcodec not found.

If I remove the --enable-aml flag configure runs with no error, but of course without the hardware decoders. I don't understand, why the aml libs are not found even when they are installed to the standard lib directory AND I explicitly point to the directory containing the original build. At least one of the libs should be found. Also leaving out the "make install" or the CFLAGS doesn't work either.
Any suggestion is welcome!

I'm compiling natively on the C2 running Debian (DietPi distro).

[meveric]

you should just install aml-libs-odroid instead of trying to build it yourself, since the "make install" command probably won't work correctly to put the headers you need for building into the right place.

[fretzke]

Sure, but install from where? This is no standard Debian lib, I can simply apt-get install, or is it?

[mscdex]

Sure, but install from where? This is no standard Debian lib, I can simply apt-get install, or is it?

It's available in the odroid c2 (xenial) repo.

[meveric]

Sure, but install from where? This is no standard Debian lib, I can simply apt-get install, or is it?

DietPi is based on my Debian Jessie images and uses my repositories.
My repository has the named package, that's why I said so.
Simply using apt-get install aml-libs-odroid is all you need to do.

Sure, but install from where? This is no standard Debian lib, I can simply apt-get install, or is it?

Don't use this package! Don't mix packages from different distros!

ERROR : amcodec not found.

That error comes from here:
https://github.com/LongChair/FFmpeg/com ... 3a39dR5723

Code: Select all

+enabled aml               && { check_lib amcodec/codec.h codec_init "-lamcodec" || die "ERROR : amcodec not found."; }

You should verify that amcodec is stalled to the expected location or correct the FFMpeg source code.

[fretzke]

You guys are pure gold!

I'm not quite there, but it feels like good progress. apt-get install aml-libs-odroid collided with the parts of the self compiled aml libs, what I think is a good sign. They were in the right place after all, so what I tried before seems to not have been completely wrong.

I flushed the system and started from scratch. aml-libs-odroid install without problem. codec.h is automatically placed in /usr/local/include/amcodec/ , the related libs in /usr/local/lib/amcodec/. But when running configure I still get ERROR : amcodec not found. In a desperate atempt I also copied all related files to ./amcodec/ in the ffmpeg folder, but to no surprise that wasn't successful either.

So risking to look like a complete noob here: How should the line in configure look like to search in the standard header and library folders? check_lib amcodec/codec.h codec_init "-lamcodec" obviously won't do the trick.

[crashoverride]

I would recommend just removing the check altogether. Then when you compile, "real" error messages (that are from gcc) will provide additional clues to the actual issue.

[fretzke]

Line removed, configure finishes without further errors. An odd side note: with the configure flags I posted above, the mpeg2 decoder is reported missing. I looked it up in the aml libs and indeed, only mpeg4, h264, hevc and vc1 are defined. Shoulde't the C2 be capable of decoding mpeg2 in hw???

Then trying to compile, I receive an error equal to the previous problem with configure.
The step LD ffmpeg_g throws

Code: Select all

libavcodec/libavcodec.a(amldec.o): In function `ffaml_flush':
/temp/FFmpeg/libavcodec/amldec.c:433: undefined reference to `codec_reset'

Looking at the file amldec.c, the function in question looks as follows:

Code: Select all

[…]
#40 #include "amldec.h"
[…]
#423 static void ffaml_flush(AVCodecContext *avctx)
#424 {
#425   int ret;
[…]
#433   ret = codec_reset(&aml_context->codec);

The referenced amldec.h starts with:

Code: Select all

#1 #ifndef _AMLDEC_H_
#2 #define _AMLDEC_H_
#3 
#4 #include "amlqueue.h"
#5 #include "amlion.h"
#6 #include <amcodec/codec.h>
#7 #include <amcodec/codec.h>
[…]

No, that's no typo, codec.h is included twice. But removing one of the lines doesn't change a thing.

Also looking at the codec.h file, line 23 contains: int codec_reset(codec_para_t *);. Everything is there, so why won't it build? I'm really lost here.

[crashoverride]

The step LD ffmpeg_g throws

That indicates the link phase. It means the library is not being linked. The "verbose" output will tell you the command line used and whether there is even an attempt to link it. The output of "sudo ldconfig -v" will show all libraries the linker is aware of. The amcodec library should be in the list.

[edit]
Since its an error in the linker, the issue has nothing to do with header (.h) files.

[fretzke]

The amcodec library should be in the list.

And indeed there it is. The path /usr/local/lib is listed and therein libamcodec.so -> libamcodec.so.

Since its an error in the linker, the issue has nothing to do with header (.h) files.

I was only referring to all the .h files because the error was reported in amldec.c which explicitly references to amldec.h which references to codec.h . And the function reported as „undefined reference“ is actually defined there.

The more I search for the reason why ffmpeg won't build, the less I understand what's the problem...

[crashoverride]

the less I understand what's the problem

There are two stages to making a C/C++ program: 1) compiling and 2) linking.

Compiling turns each .c file into CPU instructions (.o). Linking puts all the the .o (and .so) together into a single program. The failure is in the latter stage. The compiler can not find, or is not told about, libamcodec.so. Therefore, it can not put the program together since there is a piece missing.

A verbose build will tell you whether or not the linker is being informed about the existance of libamcodec.so. You will see "-lamcodec" on the command line. If its missing, you need to modify the Makefile. If its present, you need to modify the library search path ("-L/usr/local/lib") to let the linker know where it can be found.

[fretzke]

@crashoverride: Thanks for that very well understandable explanation!

It turned out, it was actually a combination of both. The command was missing "-lamcodec", plus "-lamadec" and "-lamavutils" were also required.

And the library path also had to be added.

So now ffmpeg builds, but the next error appears. Trying to decode an h264 file with aml gives:

Also the question remains, if the C2 can decode mpeg2 in hardware. In this branch of ffmpeg this option is definately missing.

Who had thought this seemingly simple task turns out to be such an impossible endavour... Is this even possible at all???

[crashoverride]

[h264_aml @ 0x191e250] Failed to open /dev/ion

You should check the permissions on /dev/ion. By default, only root can open it. You can change that with "sudo chmod a+rw /dev/ion".

Also the question remains, if the C2 can decode mpeg2 in hardware.

Yes, C2 can decode MPEG2 in hardware. I have verified this in c2play. Support is likely missing in the ffmpeg source code.

[fretzke]

/dev/ion isn't even present.

Also the dietpi distro runs everything as root (I can already hear the security guys howling from afar...), so missing permissions is in general rather unlikely.

[crashoverride]

/dev/ion is present in the official Ubuntu image. If you are using a 3rd party image/kernel, you will need to enable it and recompile the kernel:
https://github.com/hardkernel/linux/blo ... nfig#L3921

CONFIG_ION=y

[fretzke]

Oh my, compile the kernel?!

I do really very much appreciate your profound advice! But this is so out of proportion for what I intended.

Actually I had planned to compile a package of ffmpeg with the capability to decode in hardware to move it onto a libreelec install. Other software (mainly Comskip) rely on ffmpeg and would greatly profit from hw accelleration. Unfortunately libreelec uses the Odroid's hardware for playback in Kodi, but does not include that in it's ffmpeg implementation.

Now compiling a custom kernel and rebuild libreelec with that, is clearly way to much for my very limited spare time.

Maybe I need a completely other approach.

I have a look on the error : Unable to parse option value "-1" as pixel format

Someone have an idea ?

[odroid]

Try "ffplay" command to check whether the aml decoder works or not.
You might need a Mali enabled SDL2 library to see the video.
It was included in our latest Ubuntu 18.04 Mate image.

[martos]

oh ffplay is not compiled ... i look for ...
for SDL2 i have :
libsdl2-2.0-0/stable,now 2.0.5+dfsg1-2 arm64 [installed,automatic]
libsdl2-dev/stable,now 2.0.5+dfsg1-2 arm64 [installed]
It's enought or i need a specific SDL2 with mali includ ?

[odroid]

Do you use our Ubuntu 18.04 image or meveric's Debian image?
If yes, both of them have the EGL powered SDL2 library by default.

Otherwise, you have to build it. Refer this link.

i think i find
no sdl-config !!!

ack 'sdl-config'
configure
5843: SDL_CONFIG="${cross_prefix}sdl-config"

apt-file search "sdl-config"
libsdl1.2-dev: /usr/bin/sdl-config
so
apt-get install libsdl1.2-dev

BETTER :
locate sdl-config
/usr/bin/sdl-config

[martos]

Restart compile ...

[martos]

now ffplay is compiled ... but alway the error with ffmpeg :

Unable to parse option value "-1" as pixel format

i look for this error

when i launch ffplay with h264_aml :

ffplay works with h264 codec ...

[martos]

result with h264 who works :

[martos]

it could be an error in libavcodec/amldec.c
ack 'pix_fmt' | grep aml
libavcodec/amldec.c:530: .pix_fmt = AV_PIX_FMT_AML,\
libavcodec/amldec.c:555: .pix_fmts = (const enum AVPixelFormat[]) { AV_PIX_FMT_YUV420P /*AV_PIX_FMT_AML*/, \

i am a beginner, coud you think i can force the pix_fmt value here ? or if the value is "-1" i change to a default value ?

[martos]

i try
/root/bin/ffplay -vcodec h264_aml /root/Sintel.2010.1080p.mkv
works 2 secondes after i have on error
Impossible to convert between the formats supported by the filter 'ffplay_buffer' and the filter 'auto-inserted scaler 0'

But if i use :
/root/bin/ffplay -vcodec mpeg4_aml /root/Sintel.2010.1080p.mkv
its works

So Hw aml codecs works with ffplay but not in ffmpeg (pix_fmt value?)

[martos]

i find a post with a similar a bug in ffmpeg

https://ffmpeg.org/pipermail/ffmpeg-use ... 33420.html
buffer @ 0x2873e00] Unable to parse option value "0x0" as image size
[buffer@ 0x2873e00] Unable to parse option value "-1" as pixel format
[buffer @ 0x2873e00] Unable to parse option value "0x0" as image size
[buffer @ 0x2873e00] Error setting option video_size to value 0x0.

resolution
http://git.videolan.org/?p=ffmpeg.git;a ... 83e91dbc3c

i must find the same in aml ... so diifcult for me .... and i can't ask to ffmpeg because it's a aml fork ...
And i am not a dev ...

[odroid]

Becuase I've never tried to use ffmpeg on C2, I can't help you directly.

Which OS image and kernel version do you use?
I tested some 4K/H.265 video files with "c2play" on our official Ubuntu 18.04 + Kernel 3.16 LTS image. It worked well.
