Using the Exoplayer demo app, i've replaced the existing OGG file with another OGG file and it fails the playback

Reproduction steps

1- I open the Exoplayer demo app and i select the existing OGG file with uri
2- Playback is rightly played
3- I have placed my content inside the media.exolist.json
4- I open the Exoplayer demo app and i select that file
5- Playback Failed

      {
        "name": "Google Play (Ogg/Vorbis)",
        "uri": "https://ia800300.us.archive.org/16/items/pink_fairy_book_1010_librivox/pinkfairybook_04_lang.ogg"
      },

Important: the file plays right if i use the Google Chrome navigator

I can reproduce this behaviour in the demo app, both with the URL provided and a local copy of the same file.

I think the media might be malformed. When I check it with mediainfo it doesn't list any codec information:

$ mediainfo ~/Downloads/pinkfairybook_04_lang.ogg 
General

In contrast to the Google Play (Ogg/Vorbis) file in the demo app:

$ mediainfo

However ffprobe is able to determine the file is vorbis encoded:

$ ffprobe ~/Downloads/pinkfairybook_04_lang.ogg 
Input #0, ogg, from '/usr/local/google/home/ibaker/Downloads/pinkfairybook_04_lang.ogg':

Ok i see, as you say ffprobe determine is vorbis enconded, then Exoplayer should be able to play the file.

If i paste the url to Google Chrome, it is able to playback the file with no problems with the embbeded player, so the file is playable

The error also happens with this OGG file:

https://ia802702.us.archive.org/33/items/prideandprejudice_1005_librivox/prideandprejudice_01_austen.ogg

The fact is though using the Google Chrome integrated player, it takes a long time to load and play the file. So finally i decided to recode these conflictive ogg files with Audacity and now they are playing well and fast.

This is still an issue in apps like podcast players where the app is tasked with playing whatever URL comes from the feed.
