How to batch convert multiple videos by using ffmpeg pipe uvg266?

[jiangzemin-xudamin]

I was originally using vvenc and I just came across the uvg266 today and I am not familiar with the use of this encoder. When using uvg266, if I choose to convert the original video file to YUV first, it means I have to enter the resolution every time; but if I convert to Y4M first, uvg266 skips frame headers by default, which will cause all the video to incorrectly play at 25 frames per second! .\ffmpeg -i 1.y4m -f yuv4mpegpipe -strict -2 - | .\uvg266 -i - --input-file-format y4m --qp 51 --preset faster -o output.266 When using vvenc, I can batch convert videos with the following batch command:

md temp

for %%a in (*.y4m *.mp4 *.webm *.mov *.avi *.rm *.rmvb *.flv *.3gp) do ( 
.\ffmpeg -i "%%~sa" -an -c:v libvvenc -preset 4 -b:v 0 -qp 26 ".\temp\%%~na.vvc"
)

pause

However, when I try to replace it with the uvg266, I get a flashback, what's wrong?

md temp

for %%a in (*.y4m *.mp4 *.webm *.mov *.avi *.rm *.rmvb *.flv *.3gp) do ( 
.\ffmpeg -i "%%~sa" -an -f yuv4mpegpipe -strict -2 - | .\uvg266 -i - --input-file-format y4m --qp 51 --preset faster ".\temp\%%~na.vvc"
)

pause

HOW???? This batch file will be used to batch compress images audio video. Using FFMPEG modified by Mr. MartinEesmaa, Using Exhale to convert audio, Using UVG266 to convert video, Encapsulate multimedia files using MP4BOX.

You are missing the -o flag

Sorry, unfortunately I'm not really sure what you are trying to achieve and I'm not really an expert with MP4Box
