'video/x-raw(memory:NVMM), format=(string)I420' ! fakesink silent=false -v However, it seems that its usage is limited to the ov5693 sensor until NVIDIA releases its source code or until it adds support to v4l2 to use the ISP. This plugin was created by nvidia and it has access to the ISP that helps converting from bayer to yuv suitable for the video encoders. In order to capture there are two ways: Using v4l2 or using nvcamerasrc. vlc -vv -demux h264 -h264-fps 60 issue has been reported on NVIDIA's forum Capture Once you have built the new vlc, you can run this to open a plain UDP stream for instance Sudo apt-get build-dep vlc & sudo apt-get install libtool build-essential In order to test some of the videos or incoming streams produced by the pipelines below you might need VLC installed in your Jetson module, there is a known issue with VLC version 2.2 and you need to download and install VLC 2.4 or newer, in order to do it please follow these steps: There is a plugin to convert video/x-raw to video/x-raw(memory:NVMM) At this point it is not clear what that memory is. In order to get the best performance from the gstreamer elements that use the HW accelerators they have to receive something called NVMM memory, which we could imagine is contiguous and aligned memory ('nvbuffer', 'nv_buffer', 'nvmm'). The load represent a global load of the system (4 ARMs) just to give an idea to the reader of the system capabilities.ĪRM load measured with tegrastats for Capture and encoding capabilities The second column has the ARM load of the pipeline measured in one instant, using that value and the known value for the capture process the third column estimates the load of the encoding or display process (subtract the capture load). This table tries to summarize the ARM load of different uses cases of the Jetson TX1 using gstreamer and the capture plugin. RAM 162/3854MB (lfb 845x4MB) SWAP 0/0MB (cached 0MB) cpu VDE 0 EDP limit 0 In the remaining sections of this wiki the ARM load reported by top is included for reference to the reader but tegrastats should contain the real load. This tool seems to give better statistics of the ARM cores than top. There is a tool to measure the ARM load created by NVIDIA for the Jetson TX1. ![]() Nveglstreamsrc: nveglstreamsrc: nVidia EGL Stream Nvvideosink: nvvideosink: nVidia Video SinkĮglglessink: nveglglessink: EGL/GLES vout Sink Nvcamera: nvcamerasrc: Nvidia Camera Source Omx: nvhdmioverlaysink: OpenMax HDMI Video Sink Omx: omxvp8enc: OpenMAX VP8 Video Encoder Omx: omxh265enc: OpenMAX H.265 Video Encoder Omx: omxh264enc: OpenMAX H.264 Video Encoder Omx: omxmpegaudiodec: OpenMax MP3/MP2 decoder Omx: omxwmvdec: OpenMAX WMV Video Decoder Omx: omxmpeg2videodec: OpenMAX MPEG2 Video Decoder Omx: omxvp9dec: OpenMAX VP9 Video Decoder Omx: omxvp8dec: OpenMAX VP8 Video Decoder Omx: omxh265dec: OpenMAX H.265 Video Decoder Omx: omxh264dec: OpenMAX H.264 Video Decoder Omx: omxmpeg4videodec: OpenMAX MPEG4 Video Decoder Plugins accelerated by Hardware available: Recall that this board is a quad core A57 with some hardware units dedicated to encode/decode. The camera sensor used for tests is the ov5693. The goal is to provide you some example pipelines and introduction to the board. It also includes a brief description of the sample application called nvgstcapture-1.0 and ways to measure the ARM load when encoding/decoding using NVENC, NVDEC, NVJPG, etc. ![]() The wiki page tries to describe some of the multimedia features of the platform like the NVIDIA model to handle the ISP through its custom (and close) plugin called nvcamerasrc. On this page you are going to find a set of pipelines used on Jetson TX1, specifically used with the Jetson board. Please see our GStreamer Debugging guide for help.
