Hello Team,

I want to encode two times my input video file while decoding it juste one
time.
I use doc/examples/transcoding.c
<https://ffmpeg.org/doxygen/trunk/doc_2examples_2transcoding_8c-example.html>
What I want to do is to decode and encode like the transcoding.c examples
does.
Then, when I finished the decoding and encoding loop (while(1)).
I want to call only the encoding function again in an other loop to encode
a second time without
decoding.
Ex:
First time :
while(1)
{
       if (there is a frame in the input file)
        {
              decode input video;
              encode output file;
              next streamindex;
         }

}

Second time :
while(1)
{       encode another outputfile;
}

What I want to know, is if it's possible to do that (decode only one time
an input file in a whille loop and encode it two times).
If yes, can you tell me how to do it ?

To remind you I used doc/examples/transcoding.c which decode and encode
only one time.
What I want to do is to add an other while loop to encode a second time the
same input video.

I need your help please.
Regards
