Remove contrib/ffmpeg/A02-png-sequences.patch.

Set AVPacket flags indicating key-frame for avcodec_decode_video2() call. Specifically, libav documentation states:

 * @param[in] avpkt The input AVpacket containing the input buffer.
 *            You can create such packet with av_init_packet() and by then setting
 *            data and size, some decoders might in addition need other fields like
 *            flags&AV_PKT_FLAG_KEY. All decoders are designed to use the least
 *            fields possible.
