iOS playback stopped working

Report · Aug 24, 2012

I've installed Flash Media Interactive Server 4.5 and after installation I successfully streamed to iOS devices.

Today, streaming to iOS devices, suddenly stopped working. Streaming to other Flash compatible devices works just fine.

I use JWPlayer to connect and that gives the following error message:

The video playback was aborted due to a corruption problem or because the video used features your browser did not support:

http://my.fms.url/hls-live/livepkgr/_definst_/live/mystream.m3u8

Some times, if I reload the site and try again, I do get a few seconds of playback of the live stream, then the playback stops with the same error message, and I can't seem to be able to play back the stream ever again.

I've tried deleting the .stream-files generated in the ApplicationsFolder\livepkgr\events\_definst_\live as well as the files generated in ApplicationsFolder\livepkgr\streams\_definst_\mystream but that doesn't help.

I use Adobe Media Live Encoder 3.2 to stream to the server, using H.264 and AAC.

As I mentioned, this has worked before and, as far as I remember, haven't made any configuration changes since it last worked.

Hi,

Did you made any upgrade to iOS version on your device. Also, check playing VOD streams .. Just to confirm whether there are some issues in live configurations or it is just player side issue.

To discard the player side issue, try playing on quicktime on iMac.

Also try Safari on i-devices..

Hi,

I have not made any iOS upgrades between the time it worked and now.

Playing VOD streams doesn't work either. I thought they did, but they have stopped working as well.

The VOD/Live streams makes JWPlayer report the error previously stated. When I put the URL in the error message directly into Safari on iOS I get an error saying "The operation could not be completed".

If I try playing the same URL in quicktime on OSX I get the same error message but it also includes "OSStatus error -12936).

If I try accessing the URL in a regular windows browser the m3u8 file is downloaded.

I have recently made some configuration changes to the FMS, but I was certain HLS playback worked even after those changes... now I'm not so certain any more.

The changes I've made is to not have FMS listen on port 80. Apache now listens on port 80 and not 8134.

I changed the applications folder in fms.ini to another folder. I also changed the folders for the hls-live and hls-vod config in httpd.conf for Apache to point to the same folder.

As far as I know, that's all the config changes I've made.

EDIT: I'm using FMS 4.5.0 r297

EDIT 2: I restarted FMS earlier, and now VOD streams seems to work again (though not all of them). The live streams starts, but shows a very old live stream (not what I'm streaming at the moment) and stops after a while, never showing the current live stream.

I'm still very puzzled about this intermittent working/failing behaviour.

Can you paste your httpd.conf settings here? Also when you restarted server - i hope you made sure all your streams in "livepkgr" (also .stream files in events folder) were deleted.

Report · Aug 28, 2012

I tried stopping the server and deleting the livepkgr streams and events, and when I restarted the server (and live stream) it seems to work correctly again. I do believe my live streams problems was also present some time after having done this earlier so I'm gonna stream for a bit now, stop it, then start again tomorrow to see if I can still stream correctly.

In the meantime, here's my httpd.conf as requested:

I did a bit of streaming live yesterday, and that worked on iOS devices. I stopped the stream and tried again this morning.

Now the live stream on iOS only plays the last few seconds (30 or so) from yesterday instead of showing a continous stream of todays data. Why is that?

VOD playback seems to work just as well today as yesterday.

BTW, if restarting FMS necessitates deleting some files on the server, how should I handle if the server is restarted outside of my control?

Report · Aug 29, 2012

I am getting a feeling that you are on Developer Edition - can you confirm the same. If it is - then your recording would stop after 30 minutes no matter how long you are publishing. This might be the reason why you are getting stale data.

Report · Aug 29, 2012

No, I'm on the Interactive Edition. I haven't done any purposeful changes to actually record anything, so unless the livepkgr comes with recording enabled by default, it shouldn't be recording (I don't have a main.asc file in the livepkgr application folder).

Report · Aug 29, 2012

HDS and HLS in FMS is based on f4f recording which happens in "livepkgr" (to answer your question - it does record by default and HDS/HLS Streaming is based on that recorded f4f files)

Can you check your core and applications logs of FMS and let me know what do you see when you try to stream HLS and is getting stale data.

Report · Aug 31, 2012

I was finally able to reproduce this live stream error.

Yesterday I streamed successfully for several hours. I stopped the live stream yesterday and restarted it this morning. When I now play the live stream on an iOS device I get the last seconds of yesterday's stream.

the following is in the core log:

2012-08-31

10:00:36

7772

(e)2611178

2012-08-31

And this is from the application log:
