Tobias,
I liked your ideas of:
Dim aExec As String[]
Dim sRes As String
aExec = ["cat", "/proc/meminfo"]
' Use aExec.Add() to add more arguments
Exec aExec To sRes
and (thread 'Stopping a CLI program):
Print #hFfmpeg, "q"
if you opened it For Output...
Currently I have:
Private hffmpeg as Process
Private sOutput As String
...
Dim aExec As String
...
aExec = ["ffmpeg"]
aExec.Add("-f x11grab")
aExec.Add("-s " & iScreenWidth & "x" & iScreenHeight)
aExec.Add("-i :0.0+" & iScreenLeft & "," & iScreenTop & "+nomouse")
aExec.Add("-f pulse")
aExec.Add("-i " & "$(pactl list | grep -A2 '^Source #' | grep 'Name:
.*\\.monitor$' | awk '{print $NF}' | tail -n1)")
aExec.Add("-f " & sFileFormat)
aExec.Add("-vcodec" & svcodec)
aExec.Add("-r 25")
aExec.Add("-vb 1024k")
aExec.Add("-acodec" & sacodec)
aExec.Add("-ac 2")
aExec.Add("-ab 128k")
aExec.Add("-async 1")
aExec.Add("-threads " & bThreads)
aExec.Add("-y")
aExec.Add(sVideoPath)
hffmpeg = Exec aExec Wait For Read As "Messages"
...
Public Sub Messages_Read()
Dim sLine As String
Read #Last, sLine, -256
sOutput &= sLine
End
Public Sub Messages_Kill()
Print sOutput
End
...
Ideally, I'd like to add "Write" to the Exec line (as it seems to me that it
won't go wrong if ffmpeg 'corrupts' the output file in comparison to
using"hffmpeg.Kill()") , so that I can use (in a Stop button's click event):
Print #hffmpeg, "q"
However, I can't get the syntax right. I've tried 'Write' after 'For', 'Write'
after 'Messages', 'For Write' between 'aExec' & 'For'. Is it possible to do
this?
I don't understand the explanation of using Input instead of Read &
Output instead of Write (i.e. "If you use the *INPUT* and *OUTPUT*
keywords instead of *READ* and *WRITE*, then the process is executed
inside a virtual terminal. The process will think running inside a true
terminal.virtual terminal."). What are the implications of this, e.g.
for my app?
