Use of Flash files

Hi,
I don't know. It seems me that this question was put down but I don't remember where.
Anyway, if ffmpeg doesn't take this formats, it will be not possible. So, do that for checking :
ffmpeg -formats
Thanks.

I checked with ffmpeg -formats, and it says it supports .swf Flash
files. Not sure which version it supports, however. But at least if
OpenShot could support Flash at any level, I can compile the files for
whichever format it supports (down to a certain level, anyway - version
6 or 7 is the lowest, I think).

What give you the following command with a .swf file ? I have a doubt.
melt myfile.swf
ffplay myfile.swf

Yeah, both of these commands came back with errors:

$ melt picture_presentation.swf
Failed to load "picture_presentation.swf"

$ ffplay picture_presentation.swf

[swf @ 0x84f2500]Compressed SWF format not supported
picture_presentation.swf: Input/output error

Ah It is very bad because MLT doesn't take this format and FFmpeg who is needed for MLT because they are working in a straight relation can play it.
And then (like the both can not work with ) it is impossible to implement this.
Sorry.

So, would it help for me to send a message about this to the authors of
FFmpeg or MLT?

Here are the link of their bug tracker.
FFmpeg Team : http://www.ffmpeg.org/bugreports.html
MLT Team : http://sourceforge.net/tracker/?group_id=96039&atid=613414

And about the subject you must said that the command (melt/ffpay) for this type of file doesn't work. Give us more explanations for the format (and how to have/create this file).

Good luck.
