[Cin] history for ffmpeg.C

[Andrew Randrianasulu]

I was puzzled by this

https://github.com/cinelerra-cv-team/cincv-exp-akirad-paolo/commits/master/cinelerra/ffmpeg.C

at very start it says

r413:

Add a wrapper class for ffmpeg/libavcodec routines, with examples of
use in fileyuv.  Still in progress, but works for what it does so far.

we can see familiar

#include <string.h>

#include "filebase.h"
#include "quicktime.h"
#include "ffmpeg.h"
#include "guicast.h"

FFMPEG::FFMPEG(Asset *asset) {
this->asset = asset;
codec = 0;
context = 0;
picture = 0;
got_picture = 0;
}



int FFMPEG::init(char *codec_string) {

avcodec_init();
avcodec_register_all();

so I think we can relatively accurately conclude ffmpeg.C comes from
cinCV development tree.

So, I think, license header for this specific file should include all
contributors listed in github history

Paolo Rampino
xiphmont = Monty Montgomery

Plus, of course, William!
