I use the appCodecInit to create pipeline, and there are the params:
in_width = 640, in_height = 512, in_format = NV12, in num_channels = 1, in_num_planes =2, in_buffer_depth = 6.
out_width = 640, out_height = 512, out_format = NV12, out num_channels = 1, out_num_planes =2, out_buffer_depth = 6.
and the cmd_string for the gst_parse_launch():
appsrc format=GST_FORMAT_TIME is-live=true do-timestamp=true block=false name=myAppSrc0 ! queue ! video/x-raw, width=(int)640, height=(int)512, framerate=(fraction)30/1, format=(string)NV12, interlace-mode=(string)progressive, colorimetry=(string)bt601 ! v4l2h264enc extra-controls="controls, frame_level_rate_control_enable=1, video_bitrate=10000000" ! h264parse ! mp4mux ! filesink location=output_video_0.mp4
but in function appCodecSrcinit there is an error:
gst wrapper: could not find element <myAppSrc0> in the pipeline
