Slightly Off Topic: New FFMPEG Binary

[IgnoranceIsBliss]

There is a bug in the current 'latest' binary build found on this website which has apparently now been resolved in the FFMPEG source - the bug that causes the LAME encoder to fail with an 'Output Buffer Too Small' error.

I don't suppose there's a chance of a new build appearing any time soon? I'd REALLY like to be able to encode to MP3 using the latest version, since I'm struggling to get earlier versions to output suitable video files for Windows Mobile devices.

The bug disappears if you go back to LAME 3.98
Also there is a patch proposed but not applied. Good diplomacy is yet needed as neither FFmpeg nor LAME see the, ahem, issue as an own bug.

[...] The bug disappears if you go back to LAME 3.98 [...]

How do I do that under windows?

I have tried that, but there were far too many errors when trying to compile the package ...

[...] Also there is a patch proposed but not applied [...]

Where can I find this patch?
Is it possible to apply it in windows?

[angustia]

the latest autobuilds come with lame from cvs which has this bug fixed.

I have tried version r21657 but I am still getting the error when converting a (youtube) flv video to divx:

[angustia]

hi, could you please provide full uncut ffmpeg command line + output along with a sample input file?

Thank you in advance for taking a closer look at the problem!

Hmmm... You didn't get this build from my website =) You should contact Sherpya.
With my autobuilds, the input from libfaad fails (I'll look into that), but the output to libmp3lame is fine.

[angustia]

Actually I won't look at the libfaad issue. We should rather support ffaac, and it works.

Oh, sorry, I just stumbled across this form when searching the web for the error message string.
Actually, I got this build from sourceforge.

[...] With my autobuilds, [...] the output to libmp3lame is fine [...]

Thank you, your autobuilds do the job!
