[FFmpeg-user] Old vs New Vesion of ffmpeg - Guidance needed.

[Javier Hernandez]

Thanks Moritz. I applied the changes you suggested. The result is the same: no output whatsoever.

Guys, thanks a lot for having the time to look into this. I'll keep using the old version then.

Well, that's very unfortunate. That's where all the information is.

Please add "-report" to your batch files. That will create files named program-YYYYMMDD-HHMMSS.log in the current directory. Attach them to emails to this list (unless they are very large and full of repetitive errors - then cut out a large part of the repetitions in the middle, but don't omit beginning and end).

Well, no wonder, if there is no way for you to see what is displayed.
I'm sure there's an error message. ;-) Please use the report option to check what actually went wrong.

Let me do some guessing:

convertaudio.bat:
Please change
> ffmpeg.exe -i %1 -y -acodec libmp3lame -ar 44100 -ab 64k %2 -ss %3 -t 
> %4
to
> ffmpeg.exe -i %1 -ss %3 -t %4 -y -acodec libmp3lame -ar 44100 -ab 64k 
> %2

convertvideo.bat:
Please change
> ffmpeg.exe -i %1 -s %3x%4 -b 500k -bt 100k -vcodec libx264 -acodec 
> libfaac -ar 44100 -ab 32k -ac 2 -y %2 -ss %5 -t %6
to
> ffmpeg.exe -i %1 -ss %5 -t %6 -s %3x%4 -b 500k -bt 100k -vcodec 
> libx264 -acodec libfaac -ar 44100 -ab 32k -ac 2 -y %2

Perhaps your new ffmpeg doesn't support libfaac anymore. With most recent ffmpeg, please use the native encoder (just "aac").
