The problem was with PTS and DTS of the packet. Before writing the packet to output( before av_interleaved_write_frame command) set PTS and DTS like this

if (encodedPacket.dts != AV_NOPTS_VALUE)
    encodedPacket.dts = av_rescale_q(encodedPacket.dts, outStream->codec->time_base, outStream->time_base);
