Why is my video pixelated or jagged and green?

Pixelated video contains irregular pixels with incorrect colors, preventing the video from displaying an image.

Pixelated video is different from blurred video. Blurred video is usually caused by low resolution or bitrate. In a blurred video, the image is still intact.

Green video contains jagged green blocks, preventing the video from displaying correctly.

The causes of pixelated or jagged, green video are due to any number of issues, including:

• Camera
• Third-party image enhancement SDK
• Resolution
• Video source module
• Video renderer module

Refer to following sections to troubleshoot.

1. Complete the following steps to check the camera, third-party image enhancement SDK, and resolution:

   1. Ensure that the camera works correctly.
   2. Check the third-party image enhancement SDK. If you are using a third-party image enhancement SDK, disable it and try again. If the video is no longer jagged and green, then this is the likely cause. Please contact the technical support of the third-party image enhancement SDK.
   3. Check whether the resolution is recommended by Agora. If not, change the resolution.

2. Check the video source and the video renderer:

• If the sender uses a custom source and renderer, check the custom source first and then check the custom renderer. See the sample projects for custom source and custom renderer.
• If the sender uses a custom source and an Agora Video SDK renderer, check the custom source. See the custom source sample project.
• If the sender uses an Agora Video SDK source and a custom renderer, check the custom renderer. See the custom renderer sample project.
• If the sender uses an Agora Video SDK source and an Agora Video SDK renderer, contact support@agora.io for technical support.

When the sender uses YUV data with the custom renderer, check whether you have mistakenly used the Stride parameter and the width parameter in VideoFrame.

If pixelated video appears in both the sender and the receiver, you need to check pixelated video in the sender first. If pixelated video appears in only the receiver, refer to the following steps to troubleshoot:

1. Regardless of the renderer type, check the sender first. If the sender uses a custom source, you also need to check whether the video data is correctly sent from the custom source to the Video SDK.
2. If the receiver uses custom renderer, check the custom renderer.

When the receiver uses YUV data with the custom renderer, check whether you have mistakenly used the Stride parameter and the width parameter in VideoFrame.

3. Check whether the resolution is recommended by Agora. If not, change the resolution.

• If the sender uses a custom source and renderer, when you use setVideoSource to set a custom source, check whether the data formats in getBufferType and from IVideoFrameConsumer to the SDK are consistent. If the data formats are inconsistent, update the data formats and re-check. Then check the custom renderer.
• If the sender uses a custom source and an Agora Video SDK renderer, check the custom source. When you use setVideoSource to set a custom source, check whether the data formats in getBufferType and from IVideoFrameConsumer to the SDK are consistent. If the data formats are inconsistent, update the data formats and re-check. Also check whether the video data is correctly sent from the custom source to the SDK.
• If the sender uses an Agora Video SDK source and a custom renderer, check the custom renderer.
• If the sender uses an Agora Video SDK source and an Agora Video SDK renderer, please contact support@agora.io for technical support.

In Android, if you use a custom source in the communication profile, check whether the video data format is Texture. The Agora Video SDK for Android does not support receiving video data in Texture format. You need to update the video data format to YUV and re-check the video.

If jagged, green video appears for both the sender and the receiver, you need to check jagged, green video in the sender first. If jagged, green video appears for the receiver only, refer to the following steps to troubleshoot:

• Regardless of the renderer type, check the sender first. If the sender uses a custom source, you also need to check whether the video data is correctly transmitted from the custom source to the Video SDK. When you use setVideoSource to set a custom source, check whether the data format in getBufferType and from IVideoFrameConsumer to the SDK are consistent. If the data format is inconsistent, update the data format and re-check.

• Channel name with the pixelated or jagged, green video.
• UID of the users who send and receive the pixelated or jagged, green video and types of the devices.
• Steps to reproduce the problem.
• Screenshot of the pixelated or jagged, green video.
• The time frame of the problem.
• Source and renderer type: Agora Video SDK source, custom source, Agora Video SDK renderer, or custom renderer.
• SDK log files. See How can I set the log file?

• Whether pixelated or jagged, green video is reproducible in other types of devices.
• Whether pixelated or jagged, green video is reproducible with other resolution.
• Whether pixelated or jagged, green video appears in other apps.
