Use mencoder to solve the problem of converting FFMPEG to WMV/ASF to FLV screen, and support RM/rmvb

In SS/XS, we use FFMPEG as an example. However, when converting wmv and ASF, the image is often displayed on the screen. I checked the information on the Internet and found that the parameter adjustment was invalid.
Later, I used mencoder, and the conversion was slow, but the quality was good. I tried at least a dozen WMV/ASF screens, unexpectedly, the converted FLV file is smaller than that transferred from FFMPEG.

It is worth mentioning that mencoder is slower than FFMPEG and occupies a relatively large amount of system resources. Maybe the quality of the parameters I use is relatively high. If you have time, you can adjust the parameters.

The convert. Bat Implementation of SS/Xs can be automatically converted according to the original scheduled task.

In addition, mencoder supports RM and rmvb formats, so it is added to this batch.

I used black bold to indicate the error.

The solution isHttp://www.mplayerhq.hu/design7/dload.htmlDownload the binary codec package

Uncompress the package and copy the drv43260.dll to the Windows/system32/directory.

Then start-> RUN regsvr32 drv42360.dll. The output is successful !!!! You can enable FLV.
