@lheric hey, thank you for sharing this system. I was able to build the project on my mac but when I tried to load a yuv420 8bit it didn't work.

How I get an H265 file and then its yuv420 (8bit):

# converting the h264 to h265
ffmpeg -i big_buck_bunny_720p_10mb.mp4 -c:v libx265 -b:v 500K -c:a libvorbis sample_h265.mp4
# extracting the yuv420 (8bit) from it
ffmpeg -i sample_h265.mp4 -c:v rawvideo -pix_fmt yuv420p sample_h265.yuv

I tried to load the sample_h265.yuv but then this error showed up:

[Crit]: No Video Sequence Found..
[Debug]: "ReloadFiltersCommand Execution Success!"
[Crit]: No Video Sequence Found..
[Debug]: "RefreshScreenCommand Execution Failed!"
[Debug]: "SwitchThemeCommand Execution Success!"
[Debug]: "\"/Users/leandro.moreira/src/GitlHEVCAnalyzer/decoders/HM_100\" -b \"/Users/leandro.moreira/golang/src/github.com/globocom/redis-healthy/sample_h265.yuv\" -o decoder_yuv.yuv"
[Crit]: Bitstream decoding FAILED!
Following may be the reasons for this failure:
1. Corrupted HEVC bitstream?
2. Bitstream-decoder version mismatch?
3. Non-English characters in bitstream path or analyzer pat

What am I doing wrong? Just for your info, I ran the tool mediainfo to extract the data about the files I just used:

@leandromoreira you should directly load the h.265 bitstream (raw format without any container) in the analyzer. YUV is uncompressed format dose not contain any information about resolution, MVs... I have sent you an example bitstream. You can have a try.
