Hi

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?

BRs,

Albert

Hi,
If you double click the video file, the video playback is not run with hardware acceleration. Please try gatreamer or tegra_multimedia_api.

Hi

“If you double click the video file, the video playback is not run with hardware acceleration. Please try gatreamer or tegra_multimedia_api.”

I don’t understand fully yet. In case Jeson Nano, Jeson Tx2 , it has no this problem.(Jetpack 4.2.2 has same problem)

I want to know the cause.

Thanks

Hi,
By clicking a video file in file manager, the video playback uses ffmpeg and is software decoding. On Xavier, you can run ‘sudo nvpmovel -m 0’ and ‘sudo jetson_clocks’ to get max CPU clocks and benefit decoding performance.

HI
I’ve already tested what you suggest, but the problem is pretty much the same: a little faster.Xavier is very hot!!

Jeson Nano and TX2 do not have this problem.

Please check if the hardware decoder part is ported properly.

Thanks
