Compilation error (ubuntu 13.04 x64)

[PhMetzger]

Thank for the amazing work.

Just try to compile the master version and got the following error : track.cpp:108:78: erreur: ‘avcodec_decode_audio4’ was not declared in this scope

I don't see any reason but maybe you can help ?

Thanks a lot again.

Ciao,
the reason is simple enough: the avcodec libraries you are using
are a bit outdated, and the guys writing those libraries are changing the
API at every version.... I do not have enough time to keep the code
compatible with multiple versions.

Just install the latest one (even locally in a subdirectory) and be sure to
specify INCLUDE and LIBS directory in the compilation command, the
instructions at
https://github.com/ponchio/untrunc#manual-libav-installation should
work.

Good luck,

Federico

Hi Federico,

Thanks a lot for your help, you are absolutely right ! Compilation is
now good, but I have a new problem. I deal with 4 Gb clips issued by an
EOS 5D Mk II. The atoom part is missing at the end of one of those clips.

The untrunc code is working perfectly with smaller clips (I made some
tests) but with those 4 Gb clips it failed with

terminate called after throwing an instance of 'std::bad_alloc'
   what():  std::bad_alloc
Abandon (core dumped)

I was expecting that a 64 bits version could allocate enough memory
(working on a 16 Gb box) but it seems it's not so simple.

I will try to split the damaged clip in smaller parts tomorrow, but i'm
not sure it can work like that. Maybe you have an idea ?

Thanks again for your help

I'm working on an out-of-core version, I will commit it shortly, I just need to test it a bit.

Splitting the damage clip will do you no good, unless you split it at the boundary of a packet and insert the appropriate mdat at the beginning.

I'm trying to recover some fairly large corrupt GoPro files and I'm seeing the same 'std::bad_alloc' error as PhMetzger. No compilation issues, except maybe a couple of warnings.

Thank you for writing and offering this software. I had problems and I thought I'd share if you have time / energy.
