Planar YUV 4:2:0 format not supported.

[Sukwon Choi]

Hi, I'm using WCS in AWS Marketplace to stream multiple ip camera video though rtsp in our web platform.

However, I found that some rtsp url failed to stream with WCS. (It works perfectly with VLC)

After several tests, I found that among videos using the H264 codec, videos using the YUV 4:2:0 Planar format spit errors.

Below image is codec information opened through VLC.

There were several videos that spit out errors, but they all had same 'Decoded format" Planar 4:2:0 YUV.

I want to know whether Planar YUV 4:2:0 is not officially supported or if there is another way I can do it.

Thanks.

Good day.
Please provide a public RTSP URL to test. It should be available 24/7. Use the private form to send the URL.

I just sent you a test rtsp url in the private form you updated.

Thanks.

We checked the stream. Camera SDP shows the video codec MP4V-ES which is unsupported by WCS:

WCS supports H264 or VP8 video codecs only, so adjust your stream to use one of them.

Sorry I sent you wrong rtsp url. I sent it to you again.

The stream is successfully playing on WCS build 5.2.1485.
Please update your instance to the latest WCS build 5.2.1487 and check again
You should also disable strict keyframe detection if enabled:

h264_strict_kframe_detect=false

Thanks!

I updated to WCS version 5.2.1482 (which is latest version in AWS market place). It's working well.


However, there are still unresolved cases.

I resent the new rtsp url in the private form.
