we have had problems using with omx 264 wrapper for gstreamer in the past but have seen some examples with Nivida SBCs having different features requirements: -Constant bitrate with Filler Data (for example if I set 12mbps and its a black screen it will artificially lift bitrate) -Ability to modi…

Hi, It does not add filler data. Since gst-v4l2 package is open source, you can download the source code and add it. Please download the package: https://developer.nvidia.com/embedded/L4T/r32_Release_v4.3/Sources/T210/public_sources.tbz2 We have seen limitation that it cannot go lower than 1.5Mbp…

Hi, In gstreamer, we are deprecating omx plugins. You may try v4l2 plugins such as nvv4l2h264enc. Please look at sample pipelines in gstreamer user guide .

Hey, Looked at the link and I saw nvv4l2h264enc is missing features like vbv-size which the omx seems to have Also found this https://forums.developer.nvidia.com/t/constant-bitrate-help/45736#:~:text=1.5mbps%20can%20be%20the,it%20hits%20the%20compression%20limit. It seems it may be impossible to…

Hi, We have vbv-size in v4l2 plugins. Please check [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.xiph.org/video/derf/y4m/park_joy_1080p50.y4m Run …

Hey, Thanks for clearing that up. I wasn’t able to find anything more on Filler Data and Minimum compression bitrate.

[image] DaneLLL: gst-v4l2 Hey, is the gstv4l2videoencode.c file that I need to modify ?

Hi, [image] Blue: is the gstv4l2videoencode.c file that I need to modify ? Yes. You may read the code to understand how it works and do customization.

Would the Jetson Nano VPU be fit for our project

Hi,
We have vbv-size in v4l2 plugins. Please check
