RV9-EHQ with fast 1st pass:
Here is another much requested improvement: speed up RV9-EHQ encoding. I have been saying it already is as fast as possible without any sacrifices to quality. However, this is when doing the actual encoding, and this change only affects the 1st pass of a 2-pass encode.
erv4_xVBR_x1stPass_120203.zip
How to enable
1 ) Replace erv4.dll in producer's codecs directory. Milestone 7 is recommended.
2 ) use this option in the codecProperties section of the audience.

进行编码:
使用命令行:
producer.exe -j job.rpjf
调用job工程文件进行压缩

补充:job文件的说明,之间的内容为注释.不起作用.
是文件标题信息.完成之后亦可以使用rmeditor.exe编辑更改

Separable 2-pass encoding : It is now possible to encode 1st and 2nd pass separately. Here is how:

1st pass:
Encode with the following line in in your audience:

复制代码

MyAnalysisFile.rva

Use extension .rva for the filename. Run producer in normal 2-pass mode. Now you can CTRL-C out of the 2nd pass, or let it finish normally. In any case, you can then view MyAnalysisFile.rva in the current directory, and potentially edit it. Currently I would suggest only to touch MinSuggestedQP, MaxSuggestedQP, and NumBFrames, or just view the file out of curiosity. I have not tested any changes to this file, so anything may happen. The same applies if you change any other settings between the two passes, for instance pre-filters or bitrates.

If you do not set a filename, with this special DLL, the analysis file will always be preserved. The default filename is ENCsomerandomstring.rva. This can be renamed and/or used for the 2nd pass as well, even if you did not specify a FirstPassFile option. This possibility will not exist in production build codecs, where the FirstPassFile option will be required to preserve the analysis file.

2nd pass re-start or re-encode:
Put the following in in your audience:

复制代码

MyAnalysisFile.rva

and encode with the '-dt' option to disable 2-pass. Include filename extension .rva. If you do not add the -dt option, producer will run two passes as it normally would, but with a wasted 1st pass. The reason this is necessary, is that this separable encoding mechanism is implemented in the codec itself, without producer knowing about it

HFEnhance : this is just a minor encoder improvement in preserving high frequency spatial information. It is not very visible, but is the new default. The main improvement is the 2-pass rate control above. HFEnhance can be disabled with the regkey NoHFEnhance=1 in the standard location:

[HKEY_LOCAL_MACHINE\SOFTWARE\RealNetworks\RV9]
"NoHFEnhance"=dword:00000001

patternAdaptivity: 0, 1, or 3 (2 does not work correctly). Default adaptive, when property is not present.

This parameter sets the number of discardable frames to be encoded in between each non-discardable (P or I) frame.

scalingFactor: 0 - 199. Default adaptive, when property is not present.

This parameter sets the quantization scaling factor for the discardable frames, compared to the P/I frames. 0 means same quantization.

example usage (just like the encoderComplexity for EHQ). Include the following in the section of the audience:
