Fix recording with old decoding/encoding API

Browse source 
The deprecated avcodec_decode_video2() should always the whole packet,
so there is no need to loop (cf doc/examples/demuxing_decoding.c in
FFmpeg).

This hack changed the packet size and data pointer. This broke recording
which used the same packet.
