D’autres logiciels intéressants
12 avril 2011, parOn ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...
La liste suivante correspond à des logiciels qui tendent peu ou prou à faire comme MediaSPIP ou que MediaSPIP tente peu ou prou à faire pareil, peu importe ...
On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

ffmpeg link error with CodeBlocks

FFmpegAndroid CANNOT LINK EXECUTABLE
3 mars 2020, par israfilllI used this library implementation ’com.writingminds:FFmpegAndroid:0.3.2’.
But i get an error.CANNOT LINK EXECUTABLE "/data/user/0/com.example.newapplication/files/ffmpeg" : "/data/data/com.example.newapplication/files/ffmpeg" has text relocations (https://android.googlesource.com/platform/bionic/+/master/androg-’changes-for-ndk-developers.md#Text-Relocations-Enforced-for-API-level-23)

ffmpeg code does not link (undefined reference to avcodec_register_all
28 janvier 2013, par SriramI am trying to compile a simple introductory program using
ffmpegthat tries to check if themp3codec is available. While the code compiles OK, I am facing difficulty in solving linker errors. Here is the code :#include
#include
#include <libavcodec></libavcodec>avcodec.h>
float *generateSinusoid(unsigned int sampleRate, unsigned int nSecondsAudio) {
unsigned int nsamples = (nSecondsAudio * sampleRate);
float *arr;
arr = (float*) malloc(sizeof(float) * nsamples);
int i = 0;
for(i = 0; i < nsamples; i++) {
arr[i] = 20 * sin(2.f * (M_PI) * (330/sampleRate) * i); /*frequency of 330H
z*/
}
return arr;
}
int main(int argc, char *argv[]) {
avcodec_register_all();
AVCodec *codec;
unsigned int sampleRate = 22050; /*assumed.*/
unsigned int nSecondsAudio = 4;
float *arr;
arr = (float *) malloc(sizeof(float) * nSecondsAudio * sampleRate);
/*Step 1. Generate sinusoid.*/
arr = generateSinusoid(sampleRate, nSecondsAudio);
/* Step 2. See if encoder exists.*/
/*codec = avcodec_find_encoder(AV_CODEC_ID_MP3);*/
if(!codec) { /*codec = NULL.*/
printf("MP3 codec not found!!!!");
} else {
printf("MP3 codec found!!!");
}
return 0;
}The code is compiled and linked like so :
encoding_mp3: encoding_mp3.o
gcc encoding_mp3.o -o encoding_mp3 -L/cygdrive/c/Users/Desktop/webserver/cygnus/lib/w32api -L/cygdrive/c/Users/Desktop/webserver/cygnus/ffmpeg/ffmpeg_dev/lib -lm -luser32 -lpthread -lavcodec
encoding_mp3.o: encoding_mp3.c

clean:
rm encoding_mp3.o encoding_mp3Linking gives the following error :

encoding_mp3.o: In function `main':
/cygdrive/c/Users/Desktop/webserver/cygnus/ffmpeg/work/encoding_mp3.c:31: undefined reference to `_avcodec_register_all'
collect2: ld returned 1 exit status
make: *** [encoding_mp3] Error 1I have gone through most of the threads on SO regarding this problem and here is what I have tried so far :
Put libraries at the end of all non-option arguments
Commented out code that references functions. This seems to work. The undefined referenceerrors go away after all function calls are removed, though the presence of a structAVCodecdoes not cause any problems.Any help on this is most welcome.
