I am trying to encode frames using Tegra Multimedia API. I am following the example code of “01_video_encode”. But I am stuck in the following call
// Set encoder output plane format
ret = ctx.enc->setOutputPlaneFormat(V4L2_PIX_FMT_YUV420M, ctx.width, ctx.height);
my ctx.width = 1280 and ctx.height = 720 and I am using ctx.encoder_pixfmt = V4L2_PIX_FMT_H264.
The error that I am receiving is
[ERROR] …/tegra_multimedia_api/samples/common/classes/NvV4l2ElementPlane.cpp:370) <����> :Error in VIDIOC_S_FMT: Inappropriate ioctl for device
FYI, using the same API and following the example code of the decoder “00_video_decoder” I already have implemented a H264 decoder successfully.
So, I don’t understand why for the same device it would through an exception for inappropriate ioctl.
Anybody can suggests anything?
Thanks in advance.
