This is a different, completely rewritten codec.
Several new inventions have been added

It does not currently support B frames.
But this is planned to be added in the near future.

If you compare it in zerrolatensy mode, then it is better than 264, close to 265 and better AV1 in realtime modes. Similar in level to VP9 with B frames, but has a number of unique things.

And yes, this is a realtime codec that plays in a different area than AV1

Hello!
v2.05.0
Encoding is completed without starting the second pass.
C:\>ffmpeg -i z:\space_6s.mkv -f yuv4mpegpipe - | sif1_enc.exe --avi_outp --comp_mode=vbr_all_p --vbr_stat_f=z:\sif_stat.sta --out_bitrt=1200 -o z:\test.avi -
----
Are there any plans to make friends your decoder with the MPC-BE player?

An interface that uses standard threads does not allow you to rewind the thread to the beginning of the file. Therefore, when you use it, you cannot specify multiple passes with a single key.

Use multiple program launches
C:\>ffmpeg -i z:\space_6s.mkv -f yuv4mpegpipe - | sif1_enc.exe --avi_outp --comp_mode=vbr_1_p --first_pass_mode=medium --vbr_stat_f=z:\sif_stat.sta --viz_dist=45 -o z:\test.avi

C:\>ffmpeg -i z:\space_6s.mkv -f yuv4mpegpipe - | sif1_enc.exe --avi_outp --comp_mode=vbr_2_p --first_pass_mode=medium --vbr_stat_f=z:\sif_stat.sta --out_bitrt=1200 -o z:\test.avi

Setting the VD value on the first pass affects the quality obtained on the second pass.

The DirectShow decoder uses a 10 bit p010 format, which causes a number of problems with programs that do not understand it.

Some problems with this were fixed and the DirectShow decoder was updated without increasing the version number.

On the other hand, native support for decoding the format in FFMPEG, VLC is needed.
To do this, need to open the decoder code under the GPL or BSD license.
I am not the sole owner of SIF Codec LLC and such a solution requires coordination of different interests. This is a goal in the near future.
