I've only recently started using my Android device for playing audio. |

About once a week I listen to a podcast, which is usually an MP3 I've downloaded from NPR.org. |
| 4 |
|
| 5 |
On my laptop I copy these to Google Drive (big shout to net-misc/drive) and then I can access then via Drive on my Android phone. |

Google Drive on Android seems to play these audio files on a built-in player; its only controls are to skip forwards or backwards 30 seconds, but this is adequate for podcasts. |

I have here a BBC radio show that I downloaded a couple of weeks ago with net-misc/youtube-dl. |
| 10 |
|
| 11 |
When downloaded it saves as an .mp4 file. I have also tried renaming it to .m4a but, either way, Google Drive complains "unable to process this video". |
| 12 |
|
| 13 |
How do I need to process this audio to get it to play, please? |
| 14 |

I'd obviously prefer to keep the same audio stream, rather than transcoding it. I assume that the player can handle AAC (??), it just needs to be in another container. |

Thanks in advance for any suggestions, |
