problems with ffmpeg x - trying to convert QT and AVI files to Flash

[Aylam]

hello guys,

man, i am struggling with this ffmpeg x the whole day, and reading your posts i get some comfort that i am not alone, but still... cant find my hands and feet in it... am trying to convert some quicktime or AVI files to Flash, in order to upload them to my website. i downloaded the ffmpeg X for Mac, plus the 2 other components, but couldnt really figure out how to install the flvtool 2 ....

then, i dragged the QT and AVI files into ffmpeg X, and try to convert them, but i got weird files, which wouldnt play, even on the VLC player which i downloaded... (i tried the Invert Mapping check box, but it still didnt work..). here are the messages i get:

without checking the Invert Mapping box:

Stream #0.0(eng): Audio: lpcm / 0x6D63706C, 96000 Hz, mono
Unsupported codec (id=0) for input stream #0.0

Linear PCM sound in .mov files with sample rates above 64000 Hz are not recognized by ffmpeg.
If you exported this .mov file from some other application, you should bring the sample rate down to 11025, 22050 or 44100 Hz, as only those are supported by the FLV format (22050 Hz being most common). By doing that, the re-sampling only happens once.

Thank you very much ! i'll try that tonight !
indeed, i exported these .Mov or AVI files from Final Cut Pro, where I edited them. if we're already at that, could you recommend the best settings (video and audio) i should use when exporting these files from FCP, so that they are optimal for convertion into FLV files by ffmpeg x ? (for example, is Linear PCM the best choice at all ? is H.263 the right choice for the video ? etc...)

Thanks so much for your help !

hello again,

ok, so i tried the Linear PCM sound setting you suggested (22050 Hz), and exported the clip as .mov file, and checked the box for Invert Mapping, and got an flv file. but when i tried to play it in VLC, i got an error message with the following log:

any idea why it's still not working ?

thank you again !

video codec = undf
audio codec = mp3
main error: no suitable decoder module for fourcc `undf'.
VLC probably does not support this sound or video format.

Apparently, the video codec isn't recognized (undf for undefined?). Maybe VLC isn't such a good player for FLV files...

Try QuickTime Player with the Perian component, MPlayer, SWF & FLV Player, flvThing, heck, even RealPlayer.
But the acid test is to embed it in a webpage.

[Aylam]

Thanks a lot ! will try all these !

Flash support in VLC is relatively recent. Perhaps not all the bugs have been worked out yet, or it may be that you are using an older version. IIRC, versions after 0.8.somethingbigerthan5 are needed.

That said, try Case's suggestions. Something will work!

[Aylam]

thank you !
