Based on eeb975f5

The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.
