I am totally new to this support community, so my apologies if this is not the right place/tag for this question.
We've got a number of 4310G DMPs and as our DMM is not yet operational, I decided to explore the players a little bit as standalone devices, acessing them via Web-Browser.
The issue I am facing is that no audio is coming out of the DMP when I play videos, except for MPEG, which works fine.
I have tried WMV, AVI and SWF, but the audio doesn't come out for none of these.
My firmware version is 5.2.3 and I have tried outputing the audio via HDMI to a Samsung Professional display, as well as via 3.5mm audio output to a speaker.
To make sure the audio format was suported, I loaded an MP3 file to the flash memory of the DMP and played it. All worked fine. Afterwards I embedded the same audio file into a flash project (Flash Lite 3.1, Actionscript 2.0). Worked fine on my PC, but on the player, no sound at all, only the graphics.
Ps: I have already checked the audio parameters. They seem to be correct (50 on each channel), so I am running out of ideas on what else to check/try.
Please, any help will be appreciated.
Many thanks in advance.
Solved! Go to Solution.
I assume you have confirmed that the Audio and Video Codec your content is using is mentioned in the data sheet below :
Couple of Questions :
1) Are all the DMP 4310 having this issue or only the few ?
2) If you are having the issue with all, I would examine the content's codec first. If you believe that the content has the right codecs then I would ask you to open a TAC case for further analysis. You can check the codec the Video is using by opening the file in VLC Player and clicking on Media Information. Or Use a Freeware for windows called as "MediaInfo" .
3) Are you hosting the content (Video File) on a CIFS share , Internal Flash or attached USB ?
Can you attach the MIB DUMP from the DMP to this forum so that we can take a look ?
Procedure to collect the dump : Just paste the URL in the browser https://admin@password:10.0.0.1/get_param?p=*.* replace the "password" with DMP's password and the 10.0.0.1 with the IP address of the DMP's client
Save the output in a Text file and attach it to the forum. Also if you have the actual content that is having the issue - Please attach it to the forum too.
many thanks for the quick answer. I appreciate that.
Please see below my reply to your questions.
1) I assume all of them. We've got 40 and I have tested only a dozen or so, but all I tested presented the same issue.
Would you please give me some instructions as to how to open a TAC case?
Follows the SWF file I am trying to play as well as the "fla" source file I've used to generate it.
Thanks again for the help.
Tried playing the file in my LAB DMP, Same issue with the audio, Please open a TAC case for this issue. In order to open the TAC case go to www.cisco.com and Hover over the "Support" tab, You can then open the case online or call TAC frontline support.
just one last question.
Would you happen to have Flash file with audio that plays correctly on the DMP 4310G?
I might use it as reference to my content creation.
Cisco TAC does not deal with Content creation but I decompiled your SWF file using a freeware utility -
http://www.flash-decompiler.com/ (stay with the free version of it)
As per the utility the SWF version you are using is Flash 8.
4310 supports Flash9 + AS2.0 (Flash lite 3.1)
Can you please try and recreate your content in Flash 9 and let me know if it helps ?
Also couple of things :
1) I do not have a working FLA currently with me.
2) There is a 4310 Content creation best practices guide that your Cisco SE should be able to provide you (The document is still internal and I will investigate if it can be made available on CCO)
I had put explicitly Flash Lite 3.1 with AS 2.0 in the fla. Dunno why it compiled as Flash 8. Anyways, I have changed it to Flash 9 with AS 2.0.
Unfortunately didn't help either. Behaviour is still the same.
I am growing worried with that. I need to know if the 4310G is able at all to output sound out of an swf file, because this is a must functionality in our project. Would you be able to confirm that? If it is for sure that the problem is in the content, then it is ok, I will have just to find out what I am doing wrong, but if this is a limitation on the DMP, it will be pretty much of a problem for us.
Have already contacted my sales rep. and asked them to ivestigate and open a TAC with CISCO.
Thanks again for your support.
I'm sorry but we've never supported the playback of audio inside SWF files. Nonetheless, it should be possible to play audio that syncs to your SWF. I suggest that you try using Digital Media Designer to synchronize the playback of an audio asset and a SWF animation asset. The instructions for doing this are at http://www.cisco.com/en/US/docs/video/digital_media_systems/5_x/5_2/DMD/user/guide/playlists.html#wp2150988
Please let us know if this method works for you.
With respect to another issue you raised, we recommend that you avoid using video inside a SWF because our DMPs have two processors that render assets for playback. One of these is dedicated to video. But when your video is inside a SWF, the other processor renders it. This works OK but the result is inferior as compared to the video processor.
Please see our content creation best practices at http://www.cisco.com/en/US/docs/video/digital_media_systems/5_x/5_2/DMD/best/practices/guidelines.html
I hope these guides are helpful to you and get you where you'd like to be.
thanks for the answer and for the links.
I am afraid this syncronization of playlists won't help me out because the sound must be event-driven and the events would be controlled inside the SWF file. Or did I miss something?
Would this sound playback work on the 4400G (as it supports http) if I developed that inside a ASP.NET web page instead of Flash?
We have a big digital signage project in place that is meant to bring real time production status to the production shop floor. Only after our 4310G units arrived, I found out it is not compatible with HTTP and that is why I started investigating flash as an option, but without the capability of playing sound, it won't work for us, because part of this real time production status is the audio playback when certain alarms are raised.
I appreciate the support you guys are offering. Many thanks.
After reviewing the best practices guide and your last post, I understand the workaround for getting sound out of a SWF file would be putting the audio track in a kind of dummy MPEG video, right? Would it work?
Would you happen to have a sample FLA project of such a kind (that opens a MPEG video)?
I have given it a try without sucess, but I am far from being a Flash expert. If I somehow can get it to work, I will be able to recomend project management that we use this option (at least temporarily) for our application and then I would be able to get some flash experts to help me out building the whole stuff.
What make and model LCD displays will you use for this project? There might be a way to make their speakers emit an audible beep or buzz.
WRT your question about sample content, I'm checking on that now.
I am using Samsung 460-UX3 and 400-MX3.
I am afraid this beep or buzz would not be an option because there are different kind of alarms (at least 6). So they've gotta be a real melody.
Hi Gary, hi Sagar.
Have just figured it out. Using the class MediaPlayer from the DMP 4310 API I can not only play external videos in my flash project but also mp3 files. :-)
Can hardly wait to find out what else I can do with this API.
Thank you guys for the prompt and very kind support.
