Cannot get ffmpeg2.3.3 to work with Opencv2.4.9
6 septembre 2014, par Siddharthan P RI need to open a video file in opencv2.4.9. I used the following code and I got the output :
!!! Sorry cant find the video file !!!.So I figured I need to install ffmpeg first then install opencv.
So I Uninstalled opencv and ffmpeg then tried to install ffmpeg 2.3.3 properly.
Here are the methods i tried to install ffmpeg.Method 1 :
sudo apt-get install ffmpeg.Method 2 :
Download (HTTP) : http://ffmpeg.org/releases/ffmpeg-2.3.3.tar.bz2Then i typed the following in the terminal after cd to the extracted folder.
sed -i 's/-lflite"/-lflite -lasound"/' configure &&
./configure --prefix=/usr \
--enable-gpl \
--enable-version3 \
--enable-nonfree \
--disable-static \
--enable-shared \
--disable-debug \
--enable-libass \
--enable-libfdk-aac \
--enable-libmp3lame \
--enable-libtheora \
--enable-libvorbis \
--enable-libvpx \
--enable-libx264 \
--enable-x11grab &&
make &&
gcc tools/qt-faststart.c -o tools/qt-faststartThough Method 1 works fine (in just installing ffmpeg), the problem with Method 1 is that i cannot use "./configure —enable-shared" anywhere because i cannot locate the file "configure".
The problem with method 2 is that it says
-ERROR: libass not found, after installing libass it says
-ERROR: libfdk-aac-0.1.3 not found, then
-ERROR: lame-3.8 not found, then
-ERROR: libtheora not found, here i really got tired of installing all these packages. I stopped.I am really confused how to pull this off : with Method 1 or Method 2 (both seem not to work ). Can i change the ./ configure using method 1 ?
Any help would be greatly appreciated.

Mingw-w64 - printf does not work
27 décembre 2013, par Gosha U.First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously ! The terminal just shows next row. I mean it asks for a next command. But the
ffmpeg
process is visible in task manager and it writes the output video file what I had requested !I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.
#include
#include "cmdutils.h"
const char program_name[] = "hello";
const int program_birth_year = 2013;
void show_help_default(const char *opt, const char *arg)
{
printf("zxcvbnm\n");
}
int main(int argc, char **argv)
{
printf("1234567890\n");
return 0;
}And after that I created real hello world app with MinGW-w64 and qmake without eny extra libs. And its printf does not work.
I want to prevent this behavior.
I want to make printf working in traditional manner.
How I build FFmpeg :
PKG_CONFIG_PATH=/home/developer/workspace/MinGW32fs/lib/pkgconfig/ \
SDL_CONFIG=/home/developer/workspace/MinGW32fs/bin/sdl-config \
./configure \
--prefix=/home/developer/workspace/MinGW32fs \
--extra-ldflags="-L/home/developer/workspace/MinGW32fs/lib" \
--extra-cflags="-I/home/developer/workspace/MinGW32fs/include" \
--arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32- \
--pkg-config=pkg-config --enable-libtheora --enable-libvorbis --enable-libvpx \
--enable-outdev=sdl --enable-shared --disable-static \
--disable-doc --disable-manpages --disable-podpages
make
