Encoding a single frame into H.264 via 01_video_encode

Hi! I was curious whether it is possible to encode a single YUV frame into H.264 using 01_video_encode or the multimedia API. Currently, it works when I pass in 10+ YUV frames in a single file, but whenever I only pass in one, the program breaks the pipe and segfaults. The commands and output I am receiving are shown below:

$ gst-launch-1.0 videotestsrc num-buffers=1 ! ‘video/x-raw, width=(int)1280, height=(int)720, format=(string)Y444’ ! filesink location=test_Y444.yuv

$ ./video_encode test_Y444.yuv 1280 720 H264 out_Y444.h264 --elossless -p high444

We don’t validate this use-case so it may not work properly. Generally we would expect encoding frames continuously in h264/h265 encoding. For single frame encoding, you may encode to JPEG.
