Problem saving content in WowzaStreamingEngine 4.0.0

Wowza Streaming Engine
1

Hi all.

I’m testing WowzaStreamingEngine 4.0.0, but I seem to have a problem saving content. We’re using live-record mode, and the transcoder, to produce an output FLV and MP4. However, neither of these files are being written, and there are no apparent errors in the logs. I’ve checked the permissions on the output directory and these are fine, moreover this has worked fine with a previous version (WowzaMediaServer 3.6.4).

Any thoughts as to what could be the problem?

Thanks,

Henry

Hi Henry,

Did you restart the application after changing the StreamType?

Are there any clues in the error or access logs that point to the issue?

Does it work if you use the default StorageDir?

<StorageDir>${com.wowza.wms.context.VHostConfigHome}/content</StorageDir>

Henry, this looks to be an issue with the source. What encoder are you using? Can you test with FMLE?

I did test this the other day with your original configuration and it worked with FMLE on Wowza 4.

Can you describe your stream settings?

Video and audio codecs

Bit rate

FPS and GOP length(key frame interval)

Thanks for the update Henry, glad you got this sorted out.

Hi Salvadore.

Yes, I restarted the manager (WowzaStreamingEngineManager) and the engine (WowzaStreamingEngine) between making changes. I tried changing the storage dir parameter as suggested to:

<StorageDir>${com.wowza.wms.context.VHostConfigHome}/content</StorageDir>

But still nothing is written.

Regarding the configuration, initially I tried modifying our existing (3.6.4) config (listed above) as per the migration guide, but this didn’t seem to work so I created config from scratch in the manager, then manually added the missing sections. Sadly I’m still getting nothing written.

The only entry in the error log is:

WARN    server  comment 2014-02-18      08:42:40        -       -       -       -       -       127.124 -       -       -       -       -       -       -       -       LiveReceiver.flushPacketizerDelayCommand[livedesktop/_definst_/]: Stream name is missing for too long, flushing delayed packet.

The access log has the following:

Then nothing more. In 3.6.4 there would be more output in the access log as the stream is received. Nothing in our app has changed, pointing it to 3.6.4 works but not with 4.0, so I don’t believe our app is not sending data.

I’ve listed the latest configuration I’m using below.

Many thanks,

Henry

Hi Salvadore.

This is a webcam recording from a browser based Flash recorder. I’ll test a FMLE and Wirecast based stream when I’m back in the office tomorrow.

However, recording from our existing Flash recorder has always worked fine for all previous versions of Wowza. Has version 4 become less tolerant of stream anomalies? Is there some new requirement of the source stream that we need to take into account?

Thanks,

Henry

Hi Salvadore.

I finally got back to this after a load of work on our Wowza live plugin, and the problem seems to have fixed itself :slight_smile: Well not necessarily, we’re now on version 4.0.1 which maybe addressed the issue, but regardless it’s a good result for us !

Thanks for the help on this,

Yours,

Henry

Hi Salvadore.

Just FYI, I worked out what the root cause was. It seems that the transcoder no longer works with CentOS 5.8 (which we are using for our VoD recording.) I tried CentOS 6.4, however, and the transcoder worked fine.

There’s another thread started by someone else on this topic: Transcoded stream won’t start on CentOS 5.8

Yours,

Henry
