error on compiling - Githubissues

roopa01 commented 9 years ago

i compiled this code but gives error "_CFDictionaryCreate", referenced from: _ff_vda_decoder_decode in libavcodec.a(vda.o) "_CFRelease", referenced from: _ff_vda_decoder_decode in libavcodec.a(vda.o i donot know what is the reason for this error

I need some more information to guess where is the problem.

Operating system, libavcodec version, command line and the whole log of the errors....

i am using snow leopard. Libavcodec version 0.8.16
i compiled it on terminal follow all information which is given on link but is gives error

Is it necessary to install ffmpeg before running these commonds . I tried many methods to build ffmpeg but in all cases it gives "_avcodec_decode_audio4", referenced from: this type of error means all functions which i am using from this library it gives error on all functions. thanks in advance

FIrst of all you should update to the latest version (to get rid of the avcodec_open warning.

My first guess would be that the include library the compiler is using ./libav-0.8.7/libavcodec/avcodec.h (as we can see from the first error), might not match the library used for link. (maybe the libav-0.8.7 where not compiled? or the library file is in a different path?)

To test that, launch the g++ line with the option -v, at the end of the output you should be able to see exacly which files are used.

g++ -v -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -I./libav-0.8.7 -L./libav-0.8.7/libavformat -lavformat -L./libav-0.8.7/libavcodec -lavcodec -L./libav-0.8.7/libavutil -lavutil -lpthread -lz

Ciao,

i want to use ffmpeg version 2.3.6 on 64 bit mac , snow leopard. i dont know how to complie this. I used this http://hunterford.me/compiling-ffmpeg-on-mac-os-x/ but faac,lame,libogg,pkg-config,libvorbis,libtheora,yasm,libvpx,last_x264,xvidcore-1.3.2 version are not comptiable for this ffmpeg version . kindly tell me which version would be correct for compilation of ffmpeg 2.3.6.

ponchio commented 9 years ago

Ciao, I have no idea how to compile ffmpeg on the mac, sorry.

To compile untrunc you need only the libav libraries. (i have tested successfully with 0.8.7, 0.8.16, 9.17, 10.5, while with 11.2 is not compiling at the moment.

Sorry, I am afraid google is your only option....

how to make uninstall ffmpeg and its all dependent dylib files from snow leopard.

ponchio commented 9 years ago

what?

karona75 commented 9 years ago

if you have built it from source, cd to the make file directory and run sudo make uninstall.

I was able to compile untrunc with the following setup:

OS X 10.11.4
Xcode 7.3

by doing the following:

Cloning libav (I used the GitHub mirror)
Checking out v10.2 since that was the latest version @ponchio tested with
In libav repo, running ./configure && make && make install (the install is probably not absolutely necessary, but saves a bunch of -I/path/to/libav... options when compiling untrunc)
Going back to untrunc repo, and running g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -lavformat -lavcodec -lavutil -lpthread -lz -lbz2 -liconv, note the additions of -lbz2 and -liconv to fix unresolved symbol issues for libav

Granted, I haven't really run untrunc on anything meaningful yet, but this thought this might help the next person.

bgerstle commented 8 years ago

Sorry, I forgot to mention some other modifications:

Replacing all the <endian.h> imports to point to a local "endian.h" file, which wraps all the functions that are missing on OSX:

#ifndef __UNTRUNC_ENDIAN_H__
#define __UNTRUNC_ENDIAN_H__ 1

/** compatibility header for endian.h
 * This is a simple compatibility shim to convert
 * BSD/Linux endian macros to the Mac OS X equivalents.
 * It is public domain.
 * */

#ifndef __APPLE__
    #warning "This header file (endian.h) is MacOS X specific.\n"
#endif  /* __APPLE__ */

#include <libkern/OSByteOrder.h>

#define htobe16(x) OSSwapHostToBigInt16(x)
#define htole16(x) OSSwapHostToLittleInt16(x)
#define be16toh(x) OSSwapBigToHostInt16(x)
#define le16toh(x) OSSwapLittleToHostInt16(x)

#define htobe32(x) OSSwapHostToBigInt32(x)
#define htole32(x) OSSwapHostToLittleInt32(x)
#define be32toh(x) OSSwapBigToHostInt32(x)
#define le32toh(x) OSSwapLittleToHostInt32(x)

#define htobe64(x) OSSwapHostToBigInt64(x)
#define htole64(x) OSSwapHostToLittleInt64(x)
#define be64toh(x) OSSwapBigToHostInt64(x)
#define le64toh(x) OSSwapLittleToHostInt64(x)

#endif  /* __UNTRUNC_ENDIAN_H__ */

I replaced all the old endian includes by running: sed -i'' -e 's:\<endian\.h\>:"endian.h":g' *.cpp
