[audio_video_recorder] sample_audio_video_recorder.launch doesn't work when audio_format is mp3 by default #1789

When I tried to run the audio_video_recorder sample(sample_audio_video_recorder.launch), the video did not save properly. The other sample pr2_audio_video_recorder.launch worked fine, so I'm trying to figure out the cause. As a conclusion, I think it does not work well if the audio_format is mp3.
