Allocate AVPacket for stream->pending
From FFmpeg/doc/APIchanges: 2021-03-17 - f7db77bd87 - lavc 58.133.100 - codec.h Deprecated av_init_packet(). Once removed, sizeof(AVPacket) will no longer be a part of the public ABI. Remove the has_pending boolean, which can be replaced by: stream->pending != NULL Refs #2302 <https://github.com/Genymobile/scrcpy/issues/2302>
