Hello,

I am learning ExoPlayer in order to replace it with the current player in my app. I am using the demo app as the client to play the videos currently being served to my app. However when I try to play these videos the following exception is thrown:

The peculliar thing is that the videos I am trying to play work with other players but not ExoPlayer. I looked at other issues that reported a similar issue but I was not able to use the insights in them to solve the problem.

The version of the demo app that I am using is from the master branch with last commit 0c060f4.

The file I am trying to play can be found in the following link:
http://5c856ba6cc9ed2fe2e9a-6e12211e6bcd3a3454f29c48581571ff.r59.stream.cf5.rackcdn.com/69c0f207-6c65-e511-80cd-fcaa14926e72_c624d65a-1566-e511-80cd-fcaa14926e72_87356fac-4302-e511-afdd-d0509926ddf2_android_28092015103324_986806128.mp4

I would appreciate any help.

Thank you in advance,

Despite the mp4 file extension, this is actually an FLV video file. We don't currently support FLV. It does sort of work if you patch in this change, which adds FLV support: #828. We're yet to decide whether we want to support FLV officially. Note that even with this change, you cannot seek and the player gets stuck in the buffering state at the end of the content (see below).

A couple of questions:

  • If you control the media, why are you using FLV? Can you use MP4 instead? I don't think Android officially supports FLV for the built in MediaPlayer. I don't think iOS supports FLV either, although I could be wrong. Anyway, it seems like a strange choice.
  • There seems to be something weird/broken with the server. It claims the media is ~2GB long and then prematurely closes the connection at 84MB. For example if I try and fetch the media with curl, I get:
curl http://5c856ba6cc9ed2fe2e9a-6e12211e6bcd3a3454f29c48581571ff.r59.stream.cf5.rackcdn.com/69c0f207-6c65-e511-80cd-fcaa14926e72_c624d65a-1566-e511-80cd-fcaa14926e72_87356fac-4302-e511-afdd-d0509926ddf2_android_28092015103324_986806128.mp4 > testwhat.mp4

This is broken and will cause issues. It's most likely why playback gets stuck in the buffering state when you patch in FLV support (not certain about this).

Thank you for the quick reply and the useful information. I would also like
to know what you used out that the file is in FLV format and not MP4, if
possible, so in the future I will know first to check the file file format.

Respectfully,

I used this tool. This is by no means an endorsement, but it did the job in this case!

FLV is now supported, although without seeking support currently. FLV doesn't actually contain a media index to make seeking easy, so it's unclear whether we'll ever support it. Closing the issue for now. @jeoliva can comment on whether it makes sense to add seeking support at some point, or not.

Please file a separate issue, with all of the information listed here including a link to sample media. Most likely the media you're attempting to play is not supported by Android/ExoPlayer.
