Using Ffmpeg.exe to convert an ASP function in FLV format to a call in ASP

Functions | conversions

The ASP code is as follows:

<%
Str= "D:\ffmpeg.exe"
' Video= ' D:\a.mov '
video= "D:\aaa.avi"
Simg= "D:\bbbbbb.jpg"
flv= "D:\3gp2.flv"
' Response.Write Video
Set WshShell = server. CreateObject ("Wscript.Shell")
Dim RANNUM1
Randomize
Rannum1=int (10*RND) +1
' str=str& "-i" &video& "-y-f image2-ss" &ranNum1& "-t 0.005-s 120x90" &simg
str=str& "I" &video& "-y-ab 56-ar 22050-b 500-r 15-s 320*240" &flv
' str=str& "-i" &video& "-ab 56-ar 22050-b 500-r 15-s 320x240" &flv
Isffmpeg = Wshshell.run (st*,1,**lse)
' ##################### #视频图片处理结束
If Isffmpeg = 0 Then
Response.Write str& "<br>"
End If
%>

FFmpeg parameter Description

Ffmpeg.exe-i F:\ The home of the Flash guest song. Mp3-ab 56-ar 22050-b 500-r 15-s 320x240
Ffmpeg-i F:\01.wmv-ab 56-ar 22050-b 500-r 15-s 320x240 f:\test.flv
Using the-SS parameter action (Time_off set the start time offset), you can start the transformation task from a specified point-in-time. Such as:
To transform the file format while grasping thumbnails:
Ffmpeg-i "Test.avi"-y-f image2-ss 8-t 0.001-s 350x240 ' test.jpg '
For an existing FLV capture diagram:
Ffmpeg-i "test.flv"-y-f image2-ss 8-t 0.001-s 350x240 ' test.jpg '
The time unit followed by the-SS is seconds
