Incomplete NAL Units

Wowza Streaming Engine
1

Hi,

I’ve read several threads about this problem, dealing with PL and high BR stream. So I know I’m duplicating the question, again, but I just can’t figure this out!

I’m pulling down a dvb stream with vlc, transcode it and send it on to a dedicated quad-core Xeon machine in the same rack, passing through one single GigE switch.

Wowza is configured according to the mpeg-ts guide, with modifications to enable the rtp jitter buffers.

VLC is run command line with the following command:

cvlc -vvv dvb-t:// :dvb-adapter=1 :dvb-frequency=794000000 :dvb-bandwidth=8 :dvb-caching=1000 :programs=801 --sout "#duplicate{ dst='transcode{deinterlace=1,deinterlace-mode=blend,acodec=mp4a,vcodec=h264,vb=800,scale=1,venc=x264{profile=baseline,preset=ultrafast}}:rtp{mux=ts,dst=192.168.100.202,port=50000}',select='program=801'}"

This is as basic a scenario I can think off. Still I see Incomplete NAL Units in the log. With the very low bitrate in the above example it doesn’t happen frequently, but it happens. If I increase the bitrate it becomes more frequent.

The stream is SD of either 720x576 or 1024x576.

Can someone tell me what I’m doing wrong here to fail such a simple scenario? I’ve read all the guides / threads I’ve found, exchanged both servers and switch, re-installed OSs (debian and ubuntu), tried several dvb-cards… I’m just out of ideas!

Take a look at the suggestions here (#3 specifically):

Then, I am not sure. Somewhere packets are being dropped. I would also try the packet sorter/packet loss logger config to see if you see anything there.

Charlie

You must not have the jitter buffer setup properly. Also, the jitter buffer only works if the stream is RTP. So if it is a raw MPEG-TS stream (not RTP wrapped) the jitter buffer will not work.

Charlie

5

Yes, it is RTP wrapped. Looks like packet loss logger is correct. Be sure you re-start Wowza. YOu should see log statements when the stream starts about the packet sorter.

Charlie

6

What version of VLC. It certainly could be the encoding.

Charlie

7

This only applies to Smooth Streaming. If you are going to use smooth streaming you should change the key frame interval to 2 seconds.

I might experiment with a different encoding technology.

Charlie

8

It should be in the access log.

Thanks for the swift reply Charlie.

I’ve tried that before. Beefed it up to four times the values recommended as well, same problem.

10

I should mention I’ve tried a setup with a single machine as well, having vlc stream to 127.0.0.1 and still get the same problem.

11

Yea, I’m using the jitter buffers, several seconds. I hadn’t realized it would log PL thou. This would be separate log entries from the Incomplete NAL Units? Because I don’t see it in the log anywhere. Here’s what I see:

I’m no expert on VLC, but I assume this means it’s RTP wrapped?

rtp{mux=ts,dst=192.168.100.202,port=50000}

Is there any way to show a running config of Wowza? This is the relevant section of my Application.xml:

Right, I assumed it would be in the error-log. I do see it in the access-log upon startup:

I don’t see anything about PL however. Should this be in the access- or error-log?

I still don’t see any packet loss. See log below.

What else could cause these bad packets? Could it be my encoding? Anything else? Streaming directly to another VLC clients causes no problems at all.

Latest stable VLC with latest stable x264 (both via git) running on a Ubuntu 10.10 server edition.

VLC configured with –enable-debug --disable-xcb --with-pic --disable-live555 --disable-qt4 --disable-skins2, x264 with –enable-pic --enable-shared --prefix=/usr/local. x264 encoding parameters are currently with profile baseline, preset ultrafast.

Should I be concerned about this line?
