I have an application streaming mpegts packets over udp. I have set pkt\_size=1316.

If I directly receive the above udp mpegts stream in ffplay, it plays fine. (ffplay -i udp://[ServerAddress]:[Port])

If I try to receive it through Wowza, I get lots of errors from ffplay “Broken frame packetizing”, and a highly-interrupted output.

I have configured a “Stream file” in Wowza for accepting this mpegts udp stream.

My application gets encoded video frames and packetize using libavformat library functions (av\_interleaved\_write\_frame). Anything wrong with my packetization?

C:\>ffplay rtmp://localhost:1935/live/mp4:myStream2.stream

…

Broken frame packetizing

[h264 @ 0628cde0] SPS changed in the middle of the frame

Hi,

So that we can diagnose the structure of your incoming stream, it would be best if you [take a recording of the incoming MPEG-TS stream](https://www.wowza.com/docs/how-to-record-incoming-streams-for-debugging-purposes-mpeg-ts-rtp) in Wowza. Run the recording for about 5-10 minutes, and send the resulting ts segment file, along with the conf/ and logs/ folders from your Wowza installation, to support using the [ticket submission form](https://www.wowza.com/support/open-ticket).
