I figured this out finally, but this could be changed:

+    if (argc < 3 || argc > 4) {
+        av_log(NULL, AV_LOG_ERROR, "Usage: %s input out [out2]\n",
+               argv[0]);
+        exit(1);
+    }

into

av_log(NULL, AV_LOG_ERROR,
        "Usage: %s input device:dev_name [device2:dev_name]\n", argv[0]);

and maybe not AV_LOG_ERROR but AV_LOG_INFO.

Other thing that could be better it reject input files with more than 1 
stream. But it is nice to have suck testing tool anyway.
