ffmpeg doesn't reconize sound in video file.........

[ssj2_goha]

ffmpeg" -y -r 30 -i "<%InputFile%>" -deinterlace -bitexact -vcodec h264 -coder 0 -bufsize 256 -g 250 -vlevel 30 -fixaspect -s 640x480 -b 800 -maxrate 1400 -sameq -passlogfile "<%OutputFile%>" -pass 1 -acodec aac -ac 2 -ar 48000 -ab 64 -f ipod "<%TemporaryFile%>.M4V""

ok using that command sting on a file that plays perfectly in vlc, the output file has NO sound. I noticed that when ffmpeg starts out it doesn't mention muxing or reading a audio stream. Ay idea why this would be? the input file is an unencrypted vob file.

.M4V

Ffmpeg is a stickler over output file name extensions.

[ssj2_goha]

I have encoded tons (400+) of files with this same batchfile yet this is the only one that doesn't output sound..... so m4v is no problem.

[ChrissyBoy]

What is the output from the command?

[ssj2_goha]

a working m4v file just no auido......

[ChrissyBoy]

Indeed. But ffmpeg should output some info similar to:

Anyideas because both do play with sound in vlc.......

[ChrissyBoy]

Well your ffmpeg can't see an audio stream in the input...

Can you open the file in gspot and post a screenshot?

That said you have a 18 month old version of ffmpeg and so using the latest version may well solve your issue.

[ssj2_goha]

ANy help?

[ChrissyBoy]

Well yes. There is audio (as you know as you have heard it!) - more importantly, the audio stream is bonefide. In general ffmpeg would have no issue with it but your 18 month old build does. ffmpeg development is very fluid and everyday a new build can be compiled. Either compile the latest from svn or locate the latest binary you can find. Maybe from : http://ffdshow.faireal.net/mirror/ffmpeg/

[ssj2_goha]

Got the new version from the site you suggested but now i have a new problem....... ffmpeg don't like m4v or h264............. it syas something like "no suitable file format fount for h264" now what do i do???

ps. i tried both m4v and mp4......

[ChrissyBoy]

You need a build that has been compiled with --en
able-x264

Check out: http://arrozcru.no-ip.org/ffmpeg_builds/

[celtic_druid]

The build has x264 enabled. Just that there is no ipod output format in ffmpeg. The build you were using must have been patched. Think that there were some patches on the mailing list, but I guess they never got integrated. Think there was also talk of adding an ipod target (like it currently has VCD, DVD, etc.).

[45tripp]

Kill the -bitexact, -fixaspect, and -f ipod switches.
Also -sameq is clashing with setting a bitrate. It should overide -b and be restricted by -maxrate.
I find sameq useless in any case.
Use -qmin -qmax and -qscale to set quality if you're not going to set a specific bitrate.
Bitrate must be set in bit/s or add a "k" for kilobits 256k or "M" (capital) for Mbits

ffmpeg" -y -r 30 -i "<%InputFile%>" -deinterlace -vcodec h264 -coder 0 -bufsize 256k -g 250 -vlevel 30 -s 640x480 -b 800k -maxrate 1400k -passlogfile "<%OutputFile%>" -pass 1 -acodec aac -ac 2 -ar 48000 -ab 64k "<%TemporaryFile%>.Mp4""

I don't do these conversions
Maybe you could try these:

[ssj2_goha]

I might just use the new version of ffmpeg to trascode the audi in the vobs to something the "my" version can understand. Also after i changed to the sameq setting i got much much better encodes with two pass. I'll see if that works......
