TLC - Roku Mezzmo App - Stuck "Retrieving...."

[RSCCCC]

I can't seem to get any files to play through the Mezzmo app. I originally connected to the server with the Roku Media player so device type is Roku Streaming Player. That did not work well so I tried the app and I can't seem to get anything to play it is constantly stuck in Retrieving...it looks like the transcoding is failing. I've attached one transcoding error.

Thanks!

Hi,
try going to your DeviceProfiles folder (see this thread for its location: http://forum.conceiva.com/showthread.php/467-FAQ-Where-are-device-profiles-located) and open the RokuStreamingPlayer.prf file in a text editor then in the <avcontainer id="hls" section under audio modify the aac encoder from:

<format id="aac" codec="aac" ffmpegadditional="aac+encoding" encode="1" preferredtranscoded="1">
<channels>2</channels>
</format>

To:

<format id="aac" codec="aac" ffmpegadditional="aac+encoding" encode="1" preferredtranscoded="1">
<channels>2</channels>
<samplingrate>48000</samplingrate>
</format>

Then save the file and restart your Mezzmo media server. This will force the sampling rate to 48000.

I made that change and still have the same issue with a transcoding failed message. I'm attaching the new one in case it tells you something different.

The log shows that 11024 is still being specified as the audio rate, try adding the following to the profile for the aac audio in addition to the previous change:


<maxsamplingrate>48000</maxsamplingrate>
<minsamplingrate>32000</minsamplingrate>

Hi Peter,

I gave this a try and seem to be having the same issue. Any other suggestions? I'm attaching the transcoding log. I'm also attaching the .prf file so you can give it a look to see that I'm changing it correctly.

Thanks!

Hi Robert,
can you please go to 'Media Devices' and double-click your device in the list then on the Performance tab check to see what the bitrate is set to. You may need to change the setting to a higher value or set it to Default by clicking the Default button as Mezzmo may be reducing the bitrate when transcoding to meet the bandwidth setting.

If you can send an example of the file you are transcoding to support [at] conceiva [dot] com we can try transcoding it here to reproduce the problem and find a solution.

Hi Peter,

The bitrate setting was set to 100 Mbps. I tried adjusting it up to 200 Mbps, but still having the same error. I'll send you the .avi file via support referencing the thread name. It is just a home video recording. I am able to play other formats just fine, but any .avi files just get locked and have that transcoding error. File sent.

Thanks in advance!

Thanks, we got the avi file and will test it today.

The avi file played on the Roku here using the modified profile. I have sent you the updated profile to try.
