GUI4FFMPEG limits Audio Conversion Options ?

[jksmurf]

OK, I know I could probably add this in with a command line, but GUI4FFMPEG is a GUI and I want to be able to to tell my sister how to use it ...

1. If I have an Xvid that I want to Transcode to MPEG2 (DVD) that already has the audio in MP3 format and let's say I'm happy for it to stay in that format, presumably I cannot just turn off the Encode Audio option for transcodes (to save time)? When I tried it just prompted me to save just a Video Stream.

2. When I turned encode audio back on (checked the encode audio box) and tried to choose mp3 as the audio output foprmat, it always flicked back to ac3? I could choose mp2, but NOT MP3. Is there a good reason for this restriction?

MP3 is not in the DVD Spec,Thats why it's trying to encode it to AC3.MP2 Is.

[canadateck]

You could Just save the Video file and Mux the Mp3 into it after the Encode.But again no good if your going to make a DVD.

Ahhh, I see. Thanks for that explanation.

Hmm. Actually I'm not even trying to make a DVD, just an MPEG2 file I can play back from my PC into my Hauppauge MediaMVP.

In that case I think Muxing it after would be the only way to go(I think as I have never encoded a MPeg2 with MP3 ).

Gui4ffmepg doesn't allow to use mp3 audio to create a DVD compliant mpg.
But you may paste the generated command string in a dos box and change the audio options:

ffmpeg.exe -i Test.mp4 -target pal-dvd -b 6000 -aspect 4:3 -s 720x576 -acodec copy -mbd 2 -qmin 2 -sameq -async 1 -y Test.mpg

In this case the audio will be untouched.

Thank you!

Can I ask for a feature request then for an MPEG2 (rather than a dvd option) where you can choose "Audio Unchanged" or MP3 or whatever you like?

One of the reasons to create gui4ffmpeg was to prevent that
unexperienced users produce incompliant videos.
But there is an option in the menu to bypass the video presets,
this should be extended also for audio options.

quick question for you: while i like gui4ffmpeg i was wondering is there any reason why it doesn't allow for the creation of AVC/AAC mp4 files? or why you can't access the various xvid options?

[gui4ffmpeg]

Ok, the user should be able to produce DVD, SVCD, VCD and MPEG4
from any source. XVID is a kind of MPEG4.

Some binaries of ffmpeg have problems with faad/faac.
In future versions I'll use ffmpeg from celtic_druid. There are no problems
with faad/faac.
Then you may produce special videos by creating the command string with
gui4ffmpeg, add to batch and edit the batch file

for mp4 change vcodec to h264 and acodec to aac
for xvid change vcodec to xvid

The more options available, the more complicated is the usage specially
for unexperienced users.
