Urgent Help with Wowza! Pix-elation and Screen Freezing Issues

Wowza Streaming Engine
1

Hi,

I am trying to encode H264 and trying to send a live stream through my personal android using RTP to a Wowza server. I can see the output in correct form on the device. But, there are issues with getting the video on the server. I am using RTMP for the live stream and seeing degradation in video quality, whenever, there is a movement on the screen. So, this means, there is an issue with current timing of the video frames, I am using. Now, there are three things. One is sending media (my device), medium of transfer (and encoding) and Wowza (on receiving side). This means, there is an issue with any of these things.

There is another issue with RTMP or Flash player when I am playing using Wowza. The screen is getting frozen. I have tested this on my personal computer (using the network) and also tried this with another server (in those cases I am not getting any issue). This is a clear indication, that there is an issue with Wowza.

Further, I tried changing the media players including VLC, Kodi, Gom, KM, RTE, AIMP and FFmpeg. But no success. My six sense says, there is an issue with Wowza or encoding. But, thinking about pixelation of moving frames result in more confusion.

Solutions tried:

#1

Researched the whole internet and found about RTMPDump. But the problem is, it does not fetch full data packets from Wowza.

#2:

I have tried with low pixels of 188p i.e.,. 512x188 and 256kbps. Then go to upward of quality 288p with 30fps. But, I have to use machine learning, which requires high amount of data from those frames and with low frame quality, this is not possible.

I am working with a drone (for coverage on the ground), and it is tracking the movement in a border area. This will be transferred data in binary form to the ground intermediate Android device. This device will transfer the data to nearby Wowza server. Wowza is responsible for displaying on a main center. I am using machine learning algorithms along with Wowza to classify between illegal and legal immigrants (who are moving on the ground). This is a test project and in development phase at http://militarybases.co/directory/air-station-clearwater-coast-guard-base-in-clearwater-fl-2/. If successfully implemented, it will reduce the patrol officer work by 70 to 80%. I am relying on Wowza, as it is the only thing that is making the whole system working.

Need quick answers from your side!

Thanks,

Hello MabelleCrouser,

I apologize for the late response to your post.

You are correct in your troubleshooting sequence. The issue could be with the source of the video (encoder), the way the stream is encoded at the source, the medium by which that stream travels to the ingest server (Wowza), issues with Wowza or system where Wowza is running, medium by which the packetized stream is sent from Wowza to the player, and the player itself.

It would be easier if we could see the /logs, /conf and /transcoder folders, if you are using a .stream file to pull in the stream, that would help as well, this would allow us to further isolate the issue from the Wowza side of things. It would be better to get in touch with our support team with the before mentioned folders zipped. You can open a support ticket here.

I would recommend making sure that the source stream is encoded correctly. You can check out this article for details on getting your source stream configured for best results with Wowza Streaming Engine and Wowza Streaming Cloud.

What you have described thus far seems like you could be running a very longs keyframe interval on the encoder, which is causing this issue.

Alex
