Hi:
we have product need very low encoder and decoder latency ,about 30-50ms, doesTX2 can do this? what about the TX2 bandwidth for decoder? thanks

Hi,
For low latency, we suggest use jetson_multimedia_api.
Please run

$ sudo nvpmodel -m 0
$ sudo jetson_clocks

And try

01_video_encode$ ./video_encode ~/a.yuv 1920 1080 H264 ~/a.264 --stats --max-perf
00_video_decode$ ./video_decode H264 --stats --max-perf --disable-dpb --disable-rendering ../../data/Video/sample_outdoor_car_1080p_10fps.h264

We don’t have the data, but for encode/decode latency in 1920x1080, 30-50 ms should be OK.

thanks Dane, how about the bandwidth for encoder and decoder?

Hi,
Please take a look at development guide.
It should be able to reach 4Kp60 in video encoding, although it lists 4Kp30.
