FLV FFMpeg problems
|

| Mart Gordon 2005-05-26, 5:49 pm |
| We are having problems converting FLVs that have been recorded from
webcam to FCS to Mpegs using FFMpeg. Does anyone know of any issues
regarding this.
Thanks
Mart Gordon

| Yes,
FFMPEG doesn't convert audio in FLV recorded with FCS
this is because FLV uses a proprietary algorithm for audio (Nelly Moser)
Try with option -an, this exclude the audio in the conversion
process of ffmpeg, the video will be converted for sure.
Nowadays there are only a few complex way to convert
an FCS recorded FLV in MPEG, like using a screen grabber,
or other methods.

| Thanks Fabio,
That raises a question as to whether FCS recorded FLVs can be forced to
use something like Ogg for the audio?

| FCS doesn't do any encoding, it just records (saves) the audio/video
stream to disk.
The Flash player supports Nelly Moser encoding only. For playback, it
supports Nelly Moser, MP3 and a few others I forget off the top of my
head - they are the same as the options for saving audio in Flash.
So if you want to get some format other than Nelly Moser audio, you need
to use a different tool such as Squeeze, FFMPEG, etc. to create the FLV.
I don't know of any solutions to encode and stream live in a different
format.
Hope this makes sense,

| Thanks David, what I really want to know is, is there any server
software that can convert FLV to MPEG on the fly?
I'd like to get some recommendations on this.
Regards
Mart
