RTP: missing X packets - I need some help :)

[ptoki]

I have some issues with Moi Pro + ffmpeg setup.
Details below and my question is:
How to diagnose what causes missing packets.
Is it a Moi Pro issue?
Or network setup problem?
Or my ffmpeg is faulty?

How to chack what is wrong?
Which software can validate RTP stream and tell me whether Moi and network part is working fine or not?

I have tried to look a bit into those streams with wireshark but I have no idea how to verify if packets are in order and not missing.
Stats from network card are fine. On both sides (Moi and server).

I will try to upload an attachment with ffmpeg log.

And details are as follow:

Moi Pro is set up to multicast stream through ethernet. Streamin is done by dvblast. Moi Pro is confugured purely by web interface.
It is hooked up to server with just patch cable (no switch).
Stream is about 4mbit.

ffmpeg is invoked like this:
ffmpeg -i rtp://239.255.2.1:2231 -vcodec copy -an c:\tmp\tvp1---.ts

And after launch it complains about missing packets:

VLC works but picture stutters.
Server is quite powerful (ProLiant DL585 G6 with HP multifunction network card - NC-371i)

Using Moi Pro as transcoder is not the best option.
The main pourpose of Moi Pro is to use it as multiplexer and maybe some softcam decoding.

The best advice is to get unicast mode the unscrambled channels from Moi Pro to another pc / server and to process on that server the transcoding and re-streaming optimised stream further.

Ffmpeg on the other hand is well known as being very buggy , i'd recommend you to use VLC.

Thanks for sharing info.
We will try to do some hardware components swapping but we are stuck with ffmpeg and have to deal with its problems...

[vlatko175]

Does anyone know how to tell us how to solve the problem !!!

helloooooo TBS alloooooo ???

[developer]

We have complained so many times.. We cant stream the streams to server. but no one is fixing it..
May be its not useful for rtmp streams.
