Hi Dafna,

*avcodec_free_context* actually does this:

void avcodec_free_context(AVCodecContext **pavctx)
{
       AVCodecContext *avctx = *pavctx;

       if (!avctx)
           return;

       *avcodec_close(avctx);*

       av_freep(&avctx->extradata);
       av_freep(&avctx->subtitle_header);
       av_freep(&avctx->intra_matrix);
       av_freep(&avctx->inter_matrix);
       av_freep(&avctx->rc_override);

       av_freep(pavctx);
}

>From what I know *avcodec_close* should not be used anymore in the latest
ffmpeg versions.
