I have a script that generates different combinations of H.264/265, bitrate and control-rate (0=VBR,1=CBR), e.g.: ==> h265 br=1000000 gst-launch-1.0 filesrc location=../src.mjpeg ! 'image/jpeg,framerate=200/1,width=192,height=192' ! nvjpegdec idct-method=float ! 'video/x-raw(memory:NVMM),format=I42…

Hi, Please apply the attached patch to gst-v4l2 and rebuild/replace libgstnvvideo4linux2.so. The source of gst-v4l2 is in https://developer.nvidia.com/embedded/L4T/r32_Release_v4.2/Sources/T210/public_sources.tbz2 r32_3_1_TEST_0001-gst-v4l2-set-encoder-property-after-S_FMT.zip (1.0 KB)

Hi, 1Mbps looks to be a large value for 192x192 200fps. You may try with some public y4m files such as [image] H264 vs H265 Jetson Nano Hi, For comparing h264 and h265, please use same YUV source and compare PSNR. For example, you may download the source: https://media…

As you’ll see above I tried going as low as 50kbps. The quality was noticeably worse and yet the output files were still byte-for-byte identical. Still nothing with the park_joy video: coudy@nanog:~$ gst-launch-1.0 filesrc location= park_joy_1080p50.y4m ! y4mdec ! nvvidconv ! nvv4l2h264enc bitrate…

Hi, We can reproduce the issue. Will check and update.

I’m running into the same issue with the vp9 encoder nvv4l2vp9enc (on JetPack 4.3). You can quickly test with: gst-launch-1.0 -v videotestsrc num-buffers=1000 ! nvvidconv ! 'video/x-raw(memory:NVMM)' ! nvv4l2vp9enc control-rate=0 bitrate=1000000 ! webmmux ! filesink location=test0.webm and: gst-…

Hi, Please follow this post to apply the fix.

@DaneLLL it looks like that patch only applies to H264/H265, not VP9, is that correct?

Hi, The patch is general for all encoders, not specific to H264/H265. Please give it a try.

@DaneLLL Has this patch been merged in the official release yet?

Hi, [image] anon82847370: Has this patch been merged in the official release yet? The patch is in Jetpack 4.4.1(r32.4.4).
