Compiling the transcoding.c sample, appears the struct AVFrame defined twice, in avcodec.h and frame.h.

It doesn't compile.

Your build is mixing two different FFmpeg versions:

No wonder everything breaks.

comment:3 by lqsa00, 7 years ago

I'm trying to use ffmpeg libraries on Android QT application. After compile the libraries for Android, I've created a QT project containing transcoding.c and linked against the compiled libraries.

I've must to define the INT64_C and declare extern C the includes:

#ifndef INT64_C

#define INT64_C(c) (c ## LL)

#define UINT64_C(c) (c ## ULL)


extern "C" {
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libavfilter/avfiltergraph.h>
#include <libavfilter/buffersink.h>
#include <libavfilter/buffersrc.h>
#include <libavutil/opt.h>
#include <libavutil/pixdesc.h>

When compile, appears some errors, and one of them is the AVFrame duplication.

I've attached the compile output.

Ok, thank you very much. I've installed QtAV, and I suppose that mixs the libraries.
