 Hello...
I, too, started getting those ffmpeg warnings,
even for audio files (--type=radio, --pid=b05y8r96) :

---------------------------------------------------

when I upgraded my win32 FFmpeg binary
used by GiP from v2.6.3 to v2.7 (compiled
binary courtesy of Zeranoe aka Kyle Schwarz:
http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-2.7-win32-static.7z )

The warning(s) is issued by FFmpeg >=2.7
at the one-step remuxing process from the FLV
container (downloaded by default by rtmpdump
in the "flash" modes) to the MP4 container.

 For video/audio content, the files in the MP4
container come with the .mp4 extension,
in which case you receive the pair of
[mp4 @ ........] warnings; one for the video
elementary stream (0) and the other for the
audio elementary stream (1).

 For audio files, these come with the (Apple
introduced) .m4a  extension, these contain only
the audio elementary stream (0), hence one gets
a single [ipod @ ........] warning...

As you've stated yourself, these new ffmpeg
warnings do not affect at all file playability,
or impend GiP functionality, so they can be
safely ignored...

Many regards,
Vangelis.
