I am using Jetson MMAPI encoder sample, it works fine with YUV420 types of images. The problem is that the original images are RGB and when I convert them to yuv420, since the u,v channels are half-size we lose some part of the color information which doesn’t allow us to retrieve all the original im…

Hi, Please run 01_video_encode sample to compress the YUV and check if the issue is present. If there is no issue when running 01_video_encode, it looks to be an issue in the application.

I am using a similar approach as 01 sample with similar settings, and the video is made, however the image looks greenish. My original frames are RGB so I use this conversion, to make them yuv444: [image] I tried other colorspaces (V4L2_COLORSPACE_BT2020, V4L2_COLORSPACE_RAW, V4L2_COLORSPACE_SMPT…

Hi, The issue looks to be in conversion. Would use this YUV data: $ gst-launch-1.0 videotestsrc num-buffers=150 ! 'video/x-raw, width=(int)1280, height=(int)720, format=(string)Y444' ! filesink location=~/origin.yuv As input to your application. To confirm the encoding part is good in the appli…

@DaneLLL Thank you for the suggestion. Using the gstreamer command I made a video with an arbitrary size. When I extract the the frames of origin.yuv using ffmpeg, the frames look like this: [image] . And when I feed origin.yuv into the encoder (without any change), the video frames after enco…

Hi,
YUV444 encoding is demonstrated in 01_video_encode sample. Please take a look. And please refer to the posts:
