Can Azure Kinect Viewer play an Encoded video?

Ashutosh Singla 0

I successfully recorded a video using a Kinect Azure DK device and was able to play it back using Azure Kinect Viewer. However, when I attempted to encode the video using FFmpeg with the command provided below, I encountered an issue.

ffmpeg -i .\RGB.mkv -c:v libx264 RGB_Enc.mkv

Specifically, I am unable to play the encoded video using Azure Kinect Viewer, and I receive an error message stating "Failed to open Recording." I'm seeking guidance on how to resolve this problem. I have tried different codecs (libx264, VP8, VP9, libx265), but could not playback the video.

This video contains only one channel (RGB) from the original video. I am able to play this video using Azure Kinect Viewer.

Hi @Ashutosh Singla Thank you for posting the question here. The issue you are encountering may be related to the video codec used by FFmpeg to encode the video. The Azure Kinect Viewer supports a limited set of video codecs, and not all codecs are compatible with the viewer.

To encode the video in a format that is compatible with the Azure Kinect Viewer, you can use the following FFmpeg command:

ffmpeg -i RGB.mkv -c:v libx264 -preset veryfast -tune zerolatency -profile:v high -level 4.0 -pix_fmt yuv420p -crf 18 RGB_Enc.mkv

This command uses the H.264 video codec with the libx264 encoder, which is compatible with the Azure Kinect Viewer. It also sets the video profile to "high" and the level to 4.0, which are recommended settings for H.264 video. The -crf option sets the video quality, with lower values resulting in higher quality video.

After encoding the video using this command, you should be able to play it back using the Azure Kinect Viewer. If you continue to experience issues, you may want to try encoding the video using a different codec or adjusting the encoding settings to optimize the video for playback in the Azure Kinect Viewer.

Kindly give this a try and let us know if this helps.

Hi,

Thanks for your reply. This command does not work as usual. I also checked the list of the encoders that are supported by Azure Kinect Viewer. H.265 and H.264 are the codecs that are supported by Azure Kinect Viewer.
Is Azure Kinect viewer able to play an encoded video?

Hi @Ashutosh Singla Apoloigies for the delay. Can you confirm if you are experiencing this issue with just this video file, or any other file encoded using ffmpeg?

Hi @LeelaRajeshSayana-MSFT : I am experiencing this issue with any video file encoding it with FFmpeg. I can play those files in VLC player but on Azure Kinect Viewer.
