Couldn't compile without modifying track.cpp

[ciscon]

track.cpp: In member function 'void Track::parse(Atom_, Atom_)':
track.cpp:211:47: error: 'avcodec_open' was not declared in this scope
if(avcodec_open(codec.context, codec.codec)<0)
^

Commented out 211-212

Probably related to this: #6. I need to update the code (or you to use an older version of libavcodec :P).

This is a problem I'm having. I've never used Linux before yesterday, and I'm getting pretty frustrated. I've spent a good two days just getting to this point. What should I do from here?

Ciao, sorry for late answer.

Probably the problem is you have a newer version of the avcodec library,
where the avcodec_open was discontinued and replaced with the avcodec_open2
(
https://www.ffmpeg.org/doxygen/trunk/group__lavc__core.html#ga11f785a188d7d9df71621001465b0f1d
)

It should be enough to just add the '2' to the name, but I can't be sure
because I had no time to install and test the new version.

Good luck.

Federico

@ponchio

if(avcodec_open2(codec.context, codec.codec, NULL)<0)

There is 3rd argument required in new function. I used NULL and successfully compiled the project. Restored my incomplete file, thanks a lot.

Thanks for your reply.

Made the change, it worked...however, I found a free app on the Google Play
store for android phones called Video Repair by Iwo Banas. Perfect
repair!

Using @gavvvr's amendment above worked well for me on both xubuntu 14.04 and OS X.

For linux newbies, this can be applied quickly with the following in the command line:

sed -i -e "s/if(avcodec_open(codec.context, codec.codec)<0)/if(avcodec_open2(codec.context, codec.codec, NULL)<0)/g" track.cpp

Should this not be in master?
