[FFMPEG -> VCD-MPG] How to push CBR?

[Gew]

ffmpeg -i "source.avi" -an -vcodec mpeg1video -b 1150000 -aspect 4:3 -s 352x288 -y output.mpg

The results gets VBR by default.
How do I enforce CBR through FFMPEG?


Regards.

Tried

ffmpeg -i myfile.avi -target pal-vcd vcd.mpg

?

Any diffference?

Yeah. Sorry for the stupid one. I know it's always a matter of just how hard you're willing to Google your way to the answer instead of throwing meaningless threads on-board. This time, I didn't go there in the first place, instead I dumped the long ffmpeg.exe help into a txt, searched it for strings like "cbr", "constant", "bitrate". After no results I gave it up, and threw this post!

A couple of minutes later I started flooding wicked Google strings. Suddenly, I ran over this page [with a totally different topic], but anyways, there it was, the meaningful -target switch. Tried the -vcd (or w/ further precision: -pal-vcd) switches. Finally, CBR, as desired.


Anyways..
I guess this should be a whole different topic, but when I'm at it, anyone who knows why ffmpeg (latest Win32 build) can't achieve proper MP2 output? While -target pal fixes the video encoding, I still can't seem to get an audio output that doesn't go "SCHHHHHHHHHHHHHHHHHHHHZ" (high-freq noise; real SCARY one*).

Probably not the "very" latest. MP2 audio was broken a few versions ago but seems to be fixed.

Look at the left at "Tools" to download a more recent build.

THANKS!

Gosh, I've actually suspected a bug of some kind, so I've been looking for a new Win32 build more or less every week (been stuck on svn-16596 january build for quite a while), but without sucess.

Once again, seems like I've been missing it right in front of my eyes (on the board/site I visit like every day). Just downloaded latest 0.5 (built on mars 16) and mpeg audio now works like a charm all of a sudden.

Just wonderful!
