si, di suo ffmpeg in un terminale funziona benissimo, se io prendo quello che scrive debug e lo butto in un terminale, da qualunque parte del filesystem io sia, ffmpeg inizia a leggere il file mpg e butta re fuori il file mkv codificato x265 ....
Public Sub RunEncoder()
Dim Encoded As String[] 'la lista delle path di tutti i file dalla sorgente da codificare
Dim I As Integer
Dim OutputFileName As String
Dim comando As String
Encoded = FileChooser_Sorgente.SelectedPaths
Do While Not ((bChiudo = True) Or (Encoded.count = 0)) 'fino a che non ho codificato tutti i file, oppure fino a quando non si preme "cancel"
'codifica 'ffmpeg -i "$f" -c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 "$( sed -e's/\.mpg/.mkv/g' <<< $f )"
OutputFileName = File.BaseName(Encoded[0])
OutputFileName = Replace(OutputFileName, " ", "_")
OutputFileName = FileChooser_Destinazione.Dir & "/" & OutputFileName & ".mkv"
comando = "ffmpeg -i " & Encoded[0] & " -c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 " & OutputFileName
Debug comando
Shell comando
'$hProcess = Exec ["ffmpeg", "-i", Encoded[0], "-c:v", "libx265", "-preset", "medium", "-crf", "28", "-c:a", "aac", "-b:a", "128k", "-strict -2" & user.Home & "/Scrivania/test" & ".mkv"]
'$hProcess = Exec ["ffmpeg", "-i", Encoded[0], "-c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 ", OutputFileName] Wait
'$hProcess = Exec ["ffmpeg", "-i", Encoded[0], "-c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2", FileChooser_Destinazione.Dir & "/" & "test.mkv"] Wait

'$hProcess = Shell "ffmpeg -i " & Encoded[0] & " -c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 " & FileChooser_Destinazione.Dir & "/" & OutputFileName & ".mkv"
'se la codifica e' andata bene allora lo rimuovo
Encoded.Remove(0)
Loop
ToggleButton_encode.Value = 0
End
per esempio comando mi da':
FMain.RunEncoder.119: ffmpeg -i /home/v1p3r/TG/2014/tg_01102014.mpg -c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 /home/v1p3r/TG/tg_01102014.mkv
e se io prendo il comando di ffmpeg e lo butto in un terminale, l'encoder parte senza problemi:
ffmpeg -i /home/v1p3r/TG/2014/tg_01102014.mpg -c:v libx265 -preset medium -crf 28 -c:a aac -b:a 128k -strict -2 /home/v1p3r/TG/tg_01102014.mkvffmpeg version 2.8.6-1ubuntu2 Copyright (c) 2000-2016 the FFmpeg developers

mentre dentro a gambas si ferma (la codifica, l'applicazione risponde in modo fluido) dopo aver invocato ffmpeg. Sembra come se ffmpeg facesse partire un processo separato che pero' non va a buon fine
ps: nella consolle i gambas l'output di shell comando e' tipo questo:

Ho anche provato ad inserire la creazione di un file di statistiche con l'opzione
-vstats_file " & User.Home & "/MFRfile.txt "
nel comando di ffmpeg (che da terminale genera perfettamente tale file di statistica), ma dopo l'avvio del comando da "shell comando" (nell'applicativo gambas), del file di statistiche non c'e' ne e' traccia ...
