Hello! When I run the encoding example (code inserted to the following cc-file) provided in doc/examples of the FFMpeg-library and compile it with the line *linux-y8h9:/home/anders/Programs # g++ videofecencoder.cc -lavformat -lavcodec -lavutil* * * I get the following error message: /tmp/ccDQpTY5.o: In function `video_encode_example(char const*, int)': videofecencoder.cc:(.text+0x30): undefined reference to `avcodec_find_encoder(CodecID)' videofecencoder.cc:(.text+0x75): undefined reference to `avcodec_alloc_context3(AVCodec*)' videofecencoder.cc:(.text+0x7d): undefined reference to `avcodec_alloc_frame()' videofecencoder.cc:(.text+0xfc): undefined reference to `av_opt_set(void*, char const*, char const*, int)' videofecencoder.cc:(.text+0x116): undefined reference to `avcodec_open2(AVCodecContext*, AVCodec*, AVDictionary**)' videofecencoder.cc:(.text+0x1e2): undefined reference to `av_image_alloc(unsigned char**, int*, int, int, PixelFormat, int)' videofecencoder.cc:(.text+0x330): undefined reference to `avcodec_encode_video(AVCodecContext*, unsigned char*, int, AVFrame const*)' videofecencoder.cc:(.text+0x3b3): undefined reference to `avcodec_encode_video(AVCodecContext*, unsigned char*, int, AVFrame const*)' videofecencoder.cc:(.text+0x464): undefined reference to `avcodec_close(AVCodecContext*)' videofecencoder.cc:(.text+0x46f): undefined reference to `av_free(void*)' videofecencoder.cc:(.text+0x47c): undefined reference to `av_free(void*)' videofecencoder.cc:(.text+0x487): undefined reference to `av_free(void*)' /tmp/ccDQpTY5.o: In function `main': videofecencoder.cc:(.text+0x4a8): undefined reference to `avcodec_register_all()' collect2: ld returned 1 exit status
I have tried the same using two different Ubuntu-installations. The above compilation was performed using OpenSUSE installed in a VirtualBox. I did the above at a new installation of OpenSUSE. After installing it I downloaded the required libraries using the libraries provided in the Software repository called 'PackMan'. How do I resolve this?
