Cannot analyse RTP-Stream created with VLC-Player and Wireshark #9

Closed dani-987 closed 6 years ago

dani-987 commented 6 years ago

When I'm starting analysing a stream with the online version of LIST, I get only "Unknown" streams:

listafteranalysis listdetail

The created stream is based on the stream you can get at https://archive.org/download/BigBuckBunny_124/Content/big_buck_bunny_720p_surround.mp4 . The RTP-stream was created in the following steps:

  1. strg+s
  2. add video + click on "stream"
  3. "next"
  4. select "RTP/MPEG Transport Stream" + click on "Add"
  5. IP: "224.2.2.4" Port: "5004" + click on "next"
  6. select "Video - H.264 + MP3 (MP4)" + click on "next" (transcoding activated)
  7. "stream"

The stream was recoded on the client side. The pcap-file you can donwload here: https://share.ard-zdf-box.de/s/QaS3x7aCyiCK3k3

Am I doing something wrong? Can you help me please, how to get the stream analyzed? Thank you for your help :)

@dani-987 Can you give details that would be on a SDP file (chroma sub-sampling, color depth, framerate, scan mode, etc)?

dani-987 commented 6 years ago

@promgamer: Here is a screenshot of the codec-information given by VLC-Player (sry, its german...): unbenannt

According to this screenshot the values should be: chroma sub-sampling is i think 4:2:0 YUV frame rate: 24 fps

If you can tell me how to get the other information I can tell you them too....

@dani-987 right now, we only support YUV 4:2:2

Anyway, I've downloaded your PCAP and it seems that you're sending a MPEG-TS stream, which is not a ST2110-compliant. If you want a tool to simulate 2110 traffic, maybe take a look at this.

On another note: We support ST2110-20 video, which is about uncompressed video. We do not support compressed video/codecs.

thank you for your answer :) I will try this tool and answer you later, if it works or not....

I have tried to generate an smpte stream with ffmpeg but until now I wasn't successful (never worked with ffmpeg before). In the next time I won't have time for tring it again, so I'll try it in about 2 weeks again.... I hope it's ok for you

Sure it's ok! I'll close the issue right now. Try it again when you do have time and open an issue if you need some help.
