Doesn't seem to compile anymore #10

Open rickarddahlstrand opened 11 years ago

I get this error when trying to compile on an update system.

Odd.

This is after an rpi-update just now:

You probably need a newer libav*. I forget the version I'm using.

yyolk commented 10 years ago

I am getting the same error on Arch linux.

Probably because I don't have the libav

@dickontoo @rickarddahlstrand Can I ask what distro you both are using? Have you had success in compiling it with updating libav?

dickontoo commented 10 years ago

Raspbian for me. There's a suitable libav at http://newsplodge.fluff.org/~dickon/ffmpeg.tar.bz2 which is simply a tarball of the build tree of the version I used at the time. It'll need unpacking and a 'make install'ing.

yyolk commented 10 years ago

Thanks for the package! Still compiling… but will report back.

yyolk commented 10 years ago

The ffmpeg package you provided was a nice step forward. But I'm still getting an error when trying to compile omxtx.

felixdreinulldrei commented 9 years ago

Thanks Dickontoo for OMXTX. As long as I compile this with ffmpeg 1.06 libraries, everything works well. But maybe there is a little chance for you to update this to work/compile with some more recent ffmpeg version ?? It's just because newer ffmpeg versions handle some kind of .ts streams from receiver much better than the older ffmpegs.

dickontoo commented 9 years ago

Please paste the compile session -- how does it fail?

anyone else making it work latest ffmpeg libraries?

jpdavies commented 8 years ago

[UPDATE BELOW!!!] The following worked for me. Some bits commented out, not sure they're needed since I haven't properly re-ran the guide on an un-tangled fresh install of Raspbian Jessie:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade
sudo apt-get -y install git make libmp3lame-dev libopenjpeg-dev libschroedinger-dev libspeex-dev libtheora-dev libvorbis-dev libx264-dev #libs for compiling ffmpeg
cd
wget http://ffmpeg.org/releases/ffmpeg-2.8.4.tar.bz2
tar -xf ffmpeg-2.8.4.tar.bz2
cd ffmpeg-2.8.4

make
sudo make install
# sudo apt-get autoclean && sudo apt-get clean && sudo apt-get autoremove
# sudo apt-get -y install libav-dbg libav-doc libav-tools libavcodec-dev libavfilter-dev libavformat-dev libavifile-0.7-dev libavresample-dev libavutil-dev libgroove-dev libswscale-dev # needed for omxtx?
cd
git clone https://github.com/dickontoo/omxtx
cd omxtx
nano omxtx.c

...change...

...to...

static int mapcodec(enum AVCodecID id)

...save changes, exit, then...

make

[Update 2016-01-19]

The following works on a fresh install of the "Minibian" Raspbian Jessie image: Make sure the SD card has been resized with this guide. Update the fresh install:

apt-get update && apt-get -y upgrade && apt-get -y dist-upgrade

Get the tools needed for rpi-update:

apt-get -y install curl binutils

Get rpi-update:

curl -L --output /usr/bin/rpi-update https://raw.githubusercontent.com/Hexxeh/rpi-update/master/rpi-update && chmod +x /usr/bin/rpi-update

Run the rpi-update tool:

rpi-update

Handy utils for long-running SSH compile sessions:

apt-get -y install screen reptyr

Tools & libs for compiling ffmpeg:

apt-get -y install git bzip2 gcc make libmp3lame-dev libopenjpeg-dev libschroedinger-dev libspeex-dev libtheora-dev libvorbis-dev libx264-dev

Download, extract source, ./configure, make:

wget http://ffmpeg.org/releases/ffmpeg-2.8.4.tar.bz2
tar xjf ffmpeg-2.8.4.tar.bz2
cd ffmpeg-2.8.4
./configure --enable-gpl --enable-postproc --enable-pthreads --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-shared --enable-nonfree --enable-libvorbis --enable-libspeex --enable-libschroedinger --enable-avfilter --enable-libopenjpeg --enable-version3 --enable-libmp3lame --enable-runtime-cpudetect --extra-cflags=-I/usr/local/include --extra-ldflags='-L/usr/local/lib -Xlinker -R/usr/local/lib'
make

...now wait for four hours - it is a LONG compile! Eventually, install ffmpeg, download omxtx source:

make install
cd
git clone https://github.com/dickontoo/omxtx
cd omxtx

Install your favourite text editor:

apt-get -y install nano

Edit the omxtx.c source file:

nano omxtx.c

Change...

static int mapcodec(enum CodecID id)

...to...

static int mapcodec(enum AVCodecID id)

...save and make:

make
nano /boot/config.txt

Modify the GPU memory split:

gpu_mem=128

Finally reboot to load modified configuration:

reboot

I have now followed instructions to install ffmpeg 2.8.2 and try to clone and compile omxtx on a Raspberry 3 with Pixel 1.1 (Jessie Raspberry I think). I get some compilation warnings and the linker fails. I have not seen the "@LIBAVUTIL_54" suffix before. Have I missed a step?
