[FFmpeg-user] Error message 'Could not open codec' when running FFMPEG-codec.

[Anders Branderud]

Hello!

I am running the following code:
https://docs.google.com/document/d/1DbNpoy0MHNjS3ZV-6plaVdbmvW6g08riqtIz6fBO3ZE/edit

Some excerpts:
video_encode_example("/home/anders/grb_1.mpg", CODEC_ID_MPEG4);

static void video_encode_example(const char *filename, int codec_id)
{
 {
   //For full code see document attached above.
     /* open it */
    if (avcodec_open2(c, codec, NULL) < 0) {
        fprintf(stderr, "could not open codec\n");
        exit(1);
    }

}

The message 'could not open codec' is printed out.
video_encode_example("/home/anders/grb_1.mpg", CODEC_ID_MPEG2VIDEO);
generates the same error message.

How do I resolve this?
Thanks in advance!
