Video Encoded using FFmpeg is not being played in Azure Kinect Viewer

Hi @Ashutosh Singla Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

The -c:v libx265 in your command indicates that you are using the H.265 (HEVC) codec for video compression. While H.265 offers efficient compression, not all video players or viewers may support it. To ensure that the video can be played back using the Azure Kinect Viewer, you can try encoding the video using a codec that is supported by the viewer. For example, you can try using the H.264/AVC video codec instead of H.265/HEVC. You can do this by modifying the FFmpeg command as follows.

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

Try encoding the video using simpler settings to see if that resolves the problem:

ffmpeg -i RGB.mkv -c:v libx265 -x265-params crf=18 RGG_Enc.mkv

Try converting the video to a different container format like MP4:

ffmpeg -i RGB.mkv -c:v libx265 -x265-params crf=18 RGG_Enc.mp4

Ensure that the version of Azure Kinect Viewer you're using is compatible with the H.265 codec. Sometimes, certain versions of viewers or players might not support newer codecs.

Make sure that the RGG_Enc.mkv file is located in the directory where you're trying to open it from the Azure Kinect Viewer. Double-check the file path and name for any typos or discrepancies.

It's possible that the codec parameters or the FFmpeg version you're using might be causing compatibility issues. Try to play the video on another media player or video player software to see if the issue persists.
