Sebastian Dröge 73d0cac16c libav: Update AVCodecContext lifetime to work properly with ffmpeg 7
avcodec_close() is deprecated and it's not supported anymore to re-open
a codec, so we only ever allocate the codec in set_format() now and
always free it after usage.

As part of this, also fix various memory leaks in related code paths.
