Compile error on ARM running Debian Jessie

[EQWorry]

Hi, I am trying to compile untrunc on an ARM SBC running Debian Jessie 3.10, but I am getting the following error

root@Lamer:~/Source/untrunc-master# make
untrunc:
ffmpeg: shared

mkdir .build_shared
g++ -MMD -MP -DUNTR_VERSION=\"\" -O3 -std=c++11 -g -o .build_shared/track.o -c track.cpp
g++ -MMD -MP -DUNTR_VERSION=\"\" -O3 -std=c++11 -g -o .build_shared/codec.o -c codec.cpp
codec.cpp: In constructor ‘Codec::Codec(AVCodecParameters*)’:

  codec_ = avcodec_find_decoder(c->codec_id);
                                 ^
In file included from codec.cpp:1:0:
codec.h:11:7: error: forward declaration of ‘class AVCodecParameters’
 class AVCodecParameters;
       ^

plus a few more. Is this my bad, please? Thank you. :-)

Same error as above on Ubuntu 16.04.6 LTS plus the following two: codec.cpp:28:43: error: ‘avcodec_parameters_to_context’ was not declared in this scope avcodec_parameters_to_context(context_, c); ^ codec.cpp: In member function ‘void Codec::parse(Atom*, const std::vector<unsigned int>&, const std::vector<long int>&, Atom*, bool)’: codec.cpp:57:29: error: ‘av_packet_alloc’ was not declared in this scope packet_ = av_packet_alloc(); ^ Makefile:98: recipe for target '.build_shared/codec.o' failed make: *** [.build_shared/codec.o] Error 1

I believe ffmpeg 3.1+ is required for AVCodecParameters. Try using make FF_VER=3.3.9 as described here.

Great, thank you. I saw that alternative compile section, but the library install was failing (because newer FFMPEG version is installed) and I gave up then. Once I skipped that first step and used make with specified version, all download and compile went quite fine and the app is now available. Thanks again!

but the library install was failing (because newer FFMPEG version is installed)

I wonder what library/package you are talking about.. libva-dev liblzma-dev libx11-dev libbz2-dev zlib1g-dev yasm pkg-config wget are supposed to be the requirements to build ffmpeg, they don't depend on ffmpeg. Or do they?

This is what I get:

Hmm.. have you tried apt-get -t jessie-backports install libva-dev? You surely must have considered upgrading to stretch, did you?

E: The value 'jessie-backports' is invalid for APT::Default-Release as such a release is not available in the sources

It is a legacy testing system, while trying to run Stretch I stumble upon various problems, e.g. FireFox crashing... But thanks for the suggestion. :-) And thanks for all the help with this tool as well!

Sounds like your system is pretty broken.. consider reinstalling? Anyway, seems like the problem is solved for now.
