I had use jetson sdk manager from host pc to flash jetpack 4.2.1 with deepstream sdk on Jetson Xavier,
but the sample_1080p_h264.mp4 playback was lag seriously by clicking the mp4 file in the files manager
, the sample_720p.mp4 playback was normal.
After that , I had downloaded the 1080p/720p video from
https://www.appsloveworld.com/2018/10/sample-mp4-video.html , and find the same results.
Could someone verify this problem?
