I am happy with a better solution. At least we seem to agree that it would be
useful functionality.

1.) As an alternative we could attach it to the FormatInfo in
pbutils/descriptions.c. We could have a fixed extension or a callback that
resolves it according to the content.

The api would then be 
const char *gst_pb_utils_suggest_file_name_extension(type, flags)
flags would be: has_video, has_audio

2.) or we just have three extension fields attached to FormatInfo:
audio_and_video
audio_only
video_only

and select the appropriate one based on the flags.
