[Ffmpeg-devel] Decoding images (jpeg) from an url

I need some little help on decoding images via url like:

from the following code:
    if ((rc = av_open_input_file(&ic, url, NULL, 0, NULL)) >= 0) {
      if (av_find_stream_info(ic) >= 0) {
        playable = true;

  fprintf(stderr, "FfmpegIO: url(%s) is %splayable %p (rc = %d)\n",
          (playable) ? "": "NOT ", ic, rc);

I get:
FfmpegIO: url(http://w.x.y.z:9001/disk/photo/O2385(1536x1024,0).jpg) is NOT playable (nil) (rc = -6)

It works fine for mp3 urls and with stuttering audio and video for vdr files.
FfmpegIO: url(http://w.x.y.z:9001/disk/music/O562.mp3) is playable 0x87a51c0 (rc = 0)
FfmpegIO: url(http://w.x.y.z:9001/disk/video/O4712.vdr) is playable 0x8720de0 (rc = 0)

Would be nice if some could give me a hint how to proceed.
