Thanks for your help! I am able to generate the aom executable files now
However, when i run with my test video sequence with the CLI line below, the encode process will stuck at the second pass.
CLI:
aomenc --end-usage=vbr --target-bitrate=1000 --kf-max-dist=60 --width=720 --height=480 -o output.yuv test_420_10bit_720x480.yuv
Output:
Pass 1/2 frame 1800/1801 331384B 1472b/f 44184b/s 32672 ms (55.09 fps)[K
Pass 2/2 frame 19/0 0B 32701 ms 34.86 fpm [ETA unknown] [K
Do you have any idea on this? and my input yuv is 900 frames, I wonder why the 1/2 pass will have frame=1800/1801.

The command line you posted looks like it's for the 1st pass,..
If I remember correctly, 1st pass should include:
--passes=2 --pass=1 --target-bitrate=XXXX --end-usage=vbr --fpf="PATH TO THE .stats FILE"
and 2nd pass should include:
--passes=2 --pass=2 --target-bitrate=XXXX --end-usage=vbr --fpf="PATH TO THE .stats FILE"

This is the batch files I used to run the sequences.
Quote:aomenc.exe --passes=2 --pass=1 --end-usage=vbr --target-bitrate=1000 --width=780 --height=420 --fpf=aom1.log -o output.webm park_joy_420_720p50.y4m
aomenc.exe --passes=2 --pass=2 --end-usage=vbr --target-bitrate=1000 --width=780 --height=420 --fpf=aom1.log -o output.webm park_joy_420_720p50.y4m
The output i get :
Quote:Pass 1/2 frame 500/501 92184B 1474b/f 73747b/s 6977506 us (71.66 fps)[K
Pass 2/2 frame 20/1 18046B 41031 ms 29.25 fpm [ETA 5:41:14] 18046F[K
Currently by using the command that you give, it seems like able to encode 'some' frames but it will stuck afterwards or I should say the encode speed is very slow for me.
Do you have any idea on speed this up? or this is limited by my pc hardware?

Atm. there is not much you can do about speed since av1s bitstream isn't frozen and afaik no real speed optimizations have been implemented.
That said you can change the: - '--cpu-used'
- '--tile-colums'
- '--threads'
So for example using a higher cpu-used value should increase the speed, but lower the compression ratio. (faster, but less quality for a given size)

The encoding is faster after I put in the cpu command.
But i wonder is the command line for decoding is same as encoding?
Quote:For example encoding:
aomenc.exe --passes=2 --pass=1 --end-usage=vbr --target-bitrate=1000 --width=780 --height=420 --fpf=aom1.log --cpu-used=4 --threads=8 --limit=100 -o output.webm park_joy_420_720p50.y4m
aomenc.exe --passes=2 --pass=2 --end-usage=vbr --target-bitrate=1000 --width=780 --height=420 --fpf=aom1.log --cpu-used=4 --threads=8 --limit=100 -o output.webm park_joy_420_720p50.y4m
decoding:
aomdec.exe --end-usage=vbr --target-bitrate=1000 --width=780 --height=420 --cpu-used=4 --threads=8 --limit=100 -o dec_output.webm output.webm
By the way, I am testing with the aom analyser but it is not a drop and view kind of analyser and so I still figuring out how to do the analysis with the software. Is there any recommendation software for analyse the bitstream under windows environment?
I had some experience in using Intel analyzer but the aom analyser seem like I have to run the decode process with it and the decoded result will be on a webserver?

Looking at analysers before the bitstream is at least frozen seems like a bad idea.
Any thing you encode atm. is basically just for educational purpose.
Can't help with analysing av1 content atm. since due to the not frozen bitstream I looked into it at all.

I see thanks for your info. However, I would like to know the overall PSNR performance. So, to get the PSNR result should I do the decoding in order to generate the PSNR or I can get it directly by encoding

iirc adding '--psnr' will output the PSNR after encoding.

Cu Selur I do added the --psnr into my command line, it will only output the average PSNR at the end of encoding without per frame PSNR.
Is there a command for per frame PSNR? and I tried adding the >PSNR.log at the end of command but nothing is logged to the file.

I don't see an option for a frame by frame PSNR comparision, so you probably have to do that by yourself somehow.
