Description
Just do a colorspace conversion from nv12 or yuv420p to P010le colorspace
ffmpeg -c:v h264_qsv -i "C:\Users\thx4ever\Desktop\Nova pasta\1_1_video.h264" -c:v rawvideo -pix_fmt p010le C:\P010_out.yuv

What makes you think that YUV View actually knows what P010 is and how to display it?
As far as I can tell, P010 output looks fine to me.

Check my latest added yuv file that was converted from sample_AVC to P010LE yuv from Intel Media SDK sample_decode
I can confirm that the latest yuv i added from intel media sdk Works fine to convert using ffmpeg to HEVC 10bit or H264 10bit
Also ffmpeg has a bug when encoding HEVC using Intel HEVC Software, it Always set internally the stream to 1280x736 from 1280x720, that looks bad on my HDTV, it show a green bar at botton, i dont have this problem in Intel Media SDK sample_multi_transcode, it correctly encode internally 1280x720 and ffmpeg encode has 1280x736

This has currently no similarities with a valid ticket.
If you only want to report that FFmpeg uses a name for a pix_fmt that you consider unclear: We will not change it.

I think i was unclear, what i want is convert 8bit vídeo to 10bit colorspace

What? YUVView? Why?? Just use ffplay.
Yeah, there should have been some bug in media_sdk_sample_decode, because if you will try your command, and will then ffplay p010 file with:
ffplay -video_size 1280x720 -pixel_format p010le -f rawvideo -i P010_out.yuv
it will play fine (except that it defaults to BT.709 matrix with sRGB primaries, as no metadata in the yuv file, but it is correct!! the avc bitstream will have the same values).
On the other hand AFAIK my old CPU does not have modern QSV stuff. I am not sure. In that case just omit -c:v h264_qsv or add instead -hwaccel cuda.
what i want is convert 8bit vídeo to 10bit colorspace
Please, do not do this. You will propagate quantization errors further in 10 bit file.
