Transcodes to play on MVP: mp2 or mp3 audio?

[jksmurf]

I find that converting Xvid to svcd mpegs ... command line:

Code:

ffmpeg -i "input file name here" -target ntsc-svcd "output file name here"

This will produce an mpeg video with mp2 audio.

If the Xvid file has the audio encoded as an mp3, which they often are, you can use this line:

Code:

ffmpeg -i "input file name here" -target ntsc-svcd -acodec copy "output file name here"

Cheers for that... I'm just a bit averse to command lines I guess....

I've never used GUI4FFMPEG (that I can recall), but if it tells ffmpeg to transcode to dvd compliant files with the '-target ntsc-dvd' option, it will default to ac3 for the audio. If you want it to use mp2 or mp3, you must tell it so, with the '-acodec' option.

GUI4FFMPEG is the cat's PJ's for me. Mine seems to have that -acodec in the generated command line (this is from x264 to MPEG2/MP2)

Code:

"C:\Documents and Settings\Kristian\Desktop\gui4ffmpeg\ffmpeg.exe" -i "E:\GBPVRVids\RugbyUnionNZvsEng061106\RugbyUnionNZvsEng061106.mp4" -target pal-dvd -b 6000 -aspect 4:3 -s 720x400 -padtop 88 -padbottom 88 [B]-acodec[/B] mp2 -ab 224 -ac 2 -mbd 2 -sameq -async 1 -y "E:\GBPVRVids\RugbyUnionNZvsEng061106\RugbyUnionNZvsEng061106_CelticDruid.mpg"

I use the ffmpeg.exe that is included with gb-pvr, version CVS, build 4759.

I use celtic druids latest (updated celtic_druid ffmpeg builds are available from http://ffdshow.faireal.net/mirror/ffmpeg/ .. You MUST use Firefox or anotehr Browser, IE7 is banned) as the one with GUI4FFMPEG couldn't "do" H264 without crashing. Mr GUI4FFMPEG recommended using it with "-sameq" replacing the autogenerated "-qmin 2".

I added the directory it is in to my windows PATH environment variable, so that I can run it from a command line in any folder.

Yeah, I just use MS's neat little "Open Command Window Here" powertool that adds a right click command line to a folder. Always makes me laugh WinXP shelling out to a DOS window... the irony :-).

I guess that would be in your case: -acodec mp2.
If you would change that in: -acodec copy it should keep the mp3 audio.
